Fw: spotkanie w celu utworzenia sieci przy okazji wizyty ApPEC SC (fwd)
by Boud Roukema 18 Jul '06

18 Jul '06

witam cosmo-pl, Wygląda jak zaczynamy się organizować w sieci :), ale część wygląda jak formalność - chyba aby moglibyśmy mieć pieniądze dla badania ? It looks like polish cosmologists and physicists are starting to organise a network. It seems to be a lot of administrative stuff - but my guess is that it's so that we can (finally) get money for research...? pozdr boud ---------- Forwarded message ---------- > Date: Mon, 17 Jul 2006 19:47:29 +0200 > From: zralek marek małpa all pl > Subject: Fw: spotkanie w celu utworzenia sieci przy okazji wizyty ApPEC SC > > > Szanowni Państwo > > Pozwalam sobie przeslac wspolny list, ktory powstał na zakonczenie spotkania > ApPEC Steering Committee w Warszawia.

WMAP 3yr data - Omega_tot \approx 1.010-1.015 :)))))
by Boud Roukema 17 Mar '06

Witam cosmo-pl, The 3-year WMAP data is now available: http://lambda.gsfc.nasa.gov/product/map/dr2/ilc_map_get.cfm As expected from the Poincare Dodecahedral Space analyses, e.g. http://arxiv.org/abs/astro-ph/0310253 Luminet et al. http://arxiv.org/abs/astro-ph/0402608 Toruń http://arxiv.org/abs/astro-ph/0412569 Aurich Lustig Steiner http://arxiv.org/abs/astro-ph/0503014 Gundermann http://arxiv.org/abs/astro-ph/0504656 Aurich Lustig Steiner the estimates of Omega_total remain in the range 1.010-1.020. :)))) Spergel et al find: http://lambda.gsfc.nasa.gov/product/map/dr2/pub_papers/threeyear/parameters… Omega_tot = 1.015 (+0.020,-0.016) WMAP-3yr + SNLS (supernova legacy survey) 1.010 (+0.016,-0.009) WMAP-3yr + HST key project on H_0 No matter how hard people try to combine different data sets, it seems that nobody can get Omega_tot much closer to 1.000 (except by assumption). In the conclusion, section 9, page 61 of Spergel et al., you'll see that after people like me have repeated ad infinitum in many, many seminars etc that WMAP does not imply a flat Universe, it only implies a "nearly flat Universe", finally, Spergel et al. have started using this expression: "The WMAP data are consistent with nearly flat universe". :) Anyway, hopefully in the next week, i and the other people who have volunteered ;) to help organise a small, "polish cosmology" workshop/meeting in Toruń, probably in May, will send out a "pre-registration" announcement... pozdr boud

DPG Physics School 2006 , 16-21 July 2006 , Bad Honnef, Germany "Dark Matter and Dark Energy" M. Bartelmann (Heidelberg), Y. Mellier (Paris), C. Wetterich (Heidelberg) Evidence is mounting that our Universe is dominated by some form of Dark Energy which drives its accelerated expansion. In addition, most of the matter in the Universe is of an unknown form which may consist of weakly interacting, cold elementary particles. The existence and the nature of Dark Matter and Dark Energy are among the most intriguing puzzles contemporary physics is confronted with. This course is intended to summarise the evidence for Dark Matter and Dark Energy, to explain current and future observations tracking down their nature and distribution, and to describe efforts of theoretical physics to develop models for both Dark Matter and Dark Energy.

EuroSummer School, 4-16 June 2006 , MARCOUX, FRANCE "Observation and data reduction with the Very Large Telescope Interferometer" SCIENTIFIC RATIONALE With the advent of large and multi-telescope arays in the past years, interferometry has reached a new stage. Interferometers have become a more common tool for astronomical observations. They have long been team instruments equipped with a few telescopes of small diameter. Because interferometers were limited to bright sources and with no imaging capabilities, only stellar physics have benefited from this instrumental breakthrough. This time is over. Thanks to the use of large telescopes, interferometers now allow to study bright as well as relatively faint objects. First observations of active galactic nuclei have been performed with the Keck interferometric Array and with VLTI allowing to study objects which were still point-like until very recently. With the increasingly large number of telescopes, interferometers are on the verge to reconstruct complex images at an unprecedented angular resolution. Interferometric facilities are becoming more and more open to non-specialist astronomers. The VLTI is a very good example. Three instruments have been opened to the astronomical community : VINCI (until 2004), MIDI and AMBER. It is one of the most powerful interferometers with four 8-m telescopes and four 1.8-meter telescopes, the latter being relocatable on the array allowing an extensive number of configurations for high quality imaging. Although it is still the beginning, VLTI is a success with several tens of astrophysical papers already published. Such a powerful tool is very promising for many astrophysical topics and outstanding science is at hand for astronomers who know how to prepare and use such observations. SCHOOL OBJECTIVE The European Southern Observatory (ESO) in collaboration with many European institutes has operated the VLTI since 2002. Institutes in Europe have teamed-up to build a first generation of instruments which are in use and available through calls for observing proposals. The operation of the first VLTI instruments has allowed to train newcomers to this technique. A second generation of more powerful instruments will be available with still better sensitivities and imaging capabilities. However the scientific outcome will be at the same level as the VLTI performance only if astronomers get prepared to interferometric observations and to the use of interferometric data and if the specialists in interferometry transmit their knowledge to the European astronomical community. With this objective in mind, we organize a summer school to train astronomers to the use of the VLTI current generation of instruments. The objective of the school, beyond learning the basics of interferometry and getting acquainted to the VLTI instruments, is to get practical training of the most important tools required to prepare interferometric observations and to process the data for astrophysical studies. A first school in 2002 had focused on observation preparation. In this sequel, attendees will in particular be trained to data reduction, model fitting and image reconstruction. The goal is that attendees be autonomous to prepare an observing proposal to use MIDI and AMBER and use the data for their own astrophysical studies. The curriculum of the school consists in general lectures for 30% of the time, practical training for 50% of it and informal seminars for the remaining of the time. A detailed agenda is available on the school web site. The school will take place over two weeks at the Chteau de Goutelas in the center of France from June 4 to June 16.

Workshop on Nongaussianity in Cosmology July 24-28 2006, Trieste, Italy This is to announce a workshop on Nongaussianity in Cosmology July 24-28 2006, to be held in Trieste, Italy. The venue is Hotel Adriatico, overlooking the Adriatic Sea and just next to Miramare Castle and its gardens. Attendance is limited to about 80 participants to encourage informality and there will be plenty of time dedicated to discussions. The primary aim of the workshop is to bring together physicists and astrophysicists with interest in topics such as observational constraints on nongaussianity in cosmic microwave background and large scale structure, novel methods for detection of nongaussianity, theoretical predictions from models of inflation and strings etc. Please bring this announcement to attention of those that may find it relevant. The workshop is financially supported by ICTP and INFN. There is no registration fee and both food and housing are subsidized by ICTP and relatively inexpensive, but the hotel fills up quickly and early registration is encouraged. More information can be found at the web site www.ictp.trieste.it/~smr1761/, where a continuously updated list of participants can be found. Deadline for registration is April 1st. Financial help is available to participants from developing countries. Further information can be obtained from the school and conference secretariat via email smr1761 at ictp.it. Prior to this activity there will be a summer school in cosmology and astroparticle physics July 10-21 at the same location. It is targeted to beginning graduate students and other non-experts with interest working in these fields. The web site for this activity is http://cdsagenda5.ictp.trieste.it/full_display.php?smr=0&ida=a05213 , where the list of lecturers can be found. Please encourage your students and others to participate. --------------------------------------------------------------------------- PNC PNC PNC http://www.iap.fr/pnc/ PNC PNC PNC PNC --------------------------------------------------------------------------- 5. KITP program, Jan 29, 2007 - Jun 1, 2007 , Santa Barbara , USA "Accretion and Explosion: the Astrophysics of Degenerate Stars" We are writing to announce the program "Accretion and Explosion: the Astrophysics of Degenerate Stars" to be held at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, in the period January 29-June 1 2007, and to alert you that applications are now being accepted. We also encourage you to inform others who you think might be interested in applying. This program concentrates on the astrophysics of accretion and explosions on white dwarfs. Though there is agreement that a Type Ia supernovae originates from a thermonuclear instability of a massive white dwarf, the astrophysical scenario remains ambiguous, as does the mode and outcome of the explosion. The medium redshift supernovae surveys are now providing important clues about the environment dependence of supernovae properties, such as spectra and light curves. These will clearly impact empirical methods that have been developed for using the observed properties of these exploding white dwarfs as distance indicators that are widely applied to determine cosmological parameters. The time is now ripe to pursue the astronomical origins of Type Ia supernovae and their present-day accreting counterparts, the physical processes that lead to increased mass of the degenerate star in a binary pair, the approach to ignition and explosion mechanisms, the production of the light curve and spectrum, and the nucleosynthetic yield. These theoretical efforts will be accelerated by the large amount of data on the supernovae, their accreting progenitors, and their constantly cooling brethren, the isolated white dwarfs. Our aim is to provide a rich environment for the proper understanding of these phenomena in terms of stellar evolution, the physics of mass transfer binaries, and the physics of thermonuclear supernovae. The application deadline is April 2, 2006. It's necessary for every participant to apply online via the KITP web site http://www.kitp.ucsb.edu/cgi-bin/WebObjects/ITPWeb.woa/ even if we have already corresponded with you about the program. KITP programs differ from many conferences and workshops in that they create a situation where scientists learn from each other and actually do substantive research, often collaborating with other participants. To foster these interactions, KITP encourages all participants to stay for at least three weeks. We understand, however, that some might not be able to manage such a long visit during the academic year. In some of these cases, we will allow short visits for the purpose of bringing exciting new results to the awareness of the participants. KITP provides office and computing facilities on its site at UC Santa Barbara and also provides help in finding living accommodations. Some level of financial support will be available, depending on the needs of the participants and availability of funds. Due to space and financial constraints, we may not be able to accommodate your preferred dates. Actual commitments of office space and financial support can be made only by written formal invitations from the KITP Director, David Gross. If you think you'd like to participate, it will help us with our planning if you could apply early, including your proposed length of stay and any financial requirements. Again, feel free to bring this program to the attention of other interested colleagues.

The conference will focus on "Challenges in Particle Astrophysics" The main topics of the meeting will include: Ultra High Energy Cosmic Rays Dark Matter and Dark Energy Cosmology Neutrinos Gravitational Waves Most of the talks will be plenary talks, but half a day will be devoted to parallel sessions with short talks. More detailed information on the conference can be found on the following Web page: http://vietnam.in2p3.fr/2006/ Here is some background on the meeting series: Since 1993, "Rencontres du Vietnam" conferences have been organized in Vietnam on various scientific topics, ranging from particle physics to biology and astrophysics. These are international conferences and have in the past brought together some of the world's leading specialists on the specific subjects addressed. These conferences have, in fact, two purposes: * The first is, of course, the presentation and analysis of the latest advances and insights in various disciplines. * But another important motivation is to provide a means for contact between the Vietnamese and Western scientific communities. One might note in this context that young Vietnamese students are very eager to learn and apply science. There is, for example, an active cosmic ray group in Hanoi, led by a well known, retired physicist from CERN. Please note that in parallel to "Challenges in Particle Astrophysics", another conference on mesoscopic physics and nanotechnologies will be held in the same venue and that the week after, the International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI) will be held in Weihai (China). --------------------------------------------------------------------------- PNC PNC PNC http://www.iap.fr/pnc/ PNC PNC PNC PNC --------------------------------------------------------------------------- 7. COSPAR SESSION E1.8 , 16-23 July 2006 , Beijing, China "Shedding New Light on Dark Matter and Dark Energy" The three-day meeting "Shedding New Light on Dark Matter and Dark Energy", session E1.8, will be held during the 36th COSPAR Scientific Assembly, in Beijing, China 16-23 July 2006 at the Beijing Institute of Technology (BIT) and Beijing Friendship Hotel. Space observations from WMAP, Chandra, XMM-Newton, and HST as well as ground-based surveys are providing fundamental insights about dark matter and dark energy. HST and ground-based observations of lensing, large scale structure, and SN Ia determine dark matter distributions and provide constraints on dark energy. WMAP observations of the CMB provide extremely precise measurements of cosmological parameters. Space-based X-ray observations map dark matter in clusters, groups, and early type galaxies, while X-ray observations of distant cluster samples yield constraints on dark energy, particularly the equation of state, which are complementary to measurements from the CMB and SN Ia. Looking to the future, planned and proposed missions including Planck, ZEUS, JDEM, DUO, and Con-X will further revolutionize the study of dark matter and dark energy. The dark matter/dark energy meeting will take place over three successive days during the week of the COSPAR assembly. Sessions will focus on: * Dark Matter Distributions Lensing X-ray Observations * Constraints on Dark Energy Supernovae CMB Large Scale Structure and Clusters of Galaxies In addition, the meeting will discuss future programs, both space and ground-based. Each topic will be introduced by one or two reviews. We invite you to participate in the meeting and to submit abstracts for talks or posters via the COSPAR WWW site (see below).

new cosmology PhD student(s) @TCfA for Oct 2005r ?
by Boud Roukema 17 Jun '05

Witam, This is the cosmo-pl mailing list - which hasn't been used much :). The idea is for discussion about cosmo research in Poland, so that not only the "inside group" get to know what's happening. It's not supposed to be nationalistic (though i guess if we repeat the word Poland often enough then we may get more cosmology funding: do i=1,100 print*,"Polska! Kosmologia dla polaków!" enddo ;) Anyway, more seriously, a bit of gossip is that several of us will be at the einstein 2005 conference in Paris next month: http://einstein2005.obspm.fr/list_particip.php A najpraktyczne pytanie jest: jeśli znasz student na końca magistera, który chce zrobić kosmologię tu w TCfA, proszę go polecasz o kontaktu (chyba poza listu, bo to raczej prywatny niż publiczny sprawy). ,,Moj" pierwszy doktorant już jest w Japonii, więc chyba mamy miejsce dla nowy(ch) doktorant(ów) w kosmologii. BTW: Wolne zasoby edukacyjne dotyczący kosmologii w po polsku rozwijają się - jeszcze to trochę słabo, ale mamy początek treści pod GFDL (GNU Free Documentation License) na wikipedii: http://pl.wikipedia.org/wiki/Kosmologia_obserwacyjna Proszę poprawij błądy, dodawaj treści, bezpośrednie na stronach wikipedii. pozdr boud PS: If you don't feel you're a cosmologist or don't want to be on the list, then read the info which should be pasted below (maybe even in Polish, since this is mailman 2.1.5). Ktokolwiek może wolnie napisuj się czy na listę czy wypisuj się od listy.

data base of clusters of galaxies
by Boud Roukema 29 Mar '02

29 Mar '02

A data base for clusters of galaxies has been created in Toulouse. This will be complementary to existing databases such as NED http://ned.ipac.caltech.edu and the CDS http://cdsweb.u-strasbg.fr It should contain bibliographic data and published observed properties of clusters, it started in October 2001 (according to the announcement, in French, it started in "October 2002" ;) ) and apparently contains a little more than 1500 clusters of which 1470 have flux measurements and 205 have estimated temperatures. The cluster database is here: http://webast.ast.obs-mip.fr/bax (BAX = Base de donn�es des Amas en rayons X, I guess) Boud

A team of 27 astronomers led by Professor George Efstathiou of the University of Cambridge has published strong evidence for the existence of dark energy using an entirely different technique. Their results show that the universe is full of dark energy, completely consistent with the earlier supernovae results. "Dark energy appears to exist and to dominate over more conventional types of matter" says Professor Efstathiou. "An explanation of the dark energy may involve String Theory, extra dimensions or even what happened before the Big Bang. At present nobody knows.

Re: rozmawianie w CAMKu-Warszawy dzisiaj
by bp＠astro.princeton.edu 14 Mar '02

There are two independent observing projects going on in Warsaw which have cosmological implications. Janusz Kaluzny of CAMK discovered (with his associates) a number of detached eclipsing binaries in several globular clusters. These are ideal objects to measure the ages, far superior to the traditional "isochrone fitting" method, which suffers from uncontrollable errors due to lack of understanding of convective envelopes (mixing length "theory". The method used by Kaluzny is based on the very robust mass-luminosity relation for stars near the main sequence turn-off point. Enclosed is the abstract of a relevant paper: astro-ph/0111089. This is the most reliable (so far) determination of the age of any globular cluster. More work will be done soon by Janusz Kaluzny and his collaborators. Another project is OGLE, and enclosed are two papers by its leader, Andrzej Udalski of the Warsaw University Observatory. The project provides the best (so far) determination of the distance to the Large Magellanic Cloud, which is the first step towards the determination of Hubble constant by the HST Key Project and other groups. OGLE will keep refining the LMC distance determination using variety of methods - stay tuned.

Piotto,and J. Hughes Detached eclipsing double line spectroscopic binaries are accurate distance indicators. They can be used for the direct determination of distances to globular clusters in which such systems can be identified. The results of major photometric surveys aimed at identification of variable stars in omega Cen are summarized. Over 43 eclipsing binaries have been identified so far in the cluster field of which only 8 objects are true detached systems. Distance and age determinations are presented for the system OGLEGC-17. The apparent distance modulus is (m-M)_{V}=14.09\pm 0.04 and the age of this binary is tau=11.8\pm 0.6 Gyr. ------------------------------------------------------ Astrophysics, abstract astro-ph/9910167 From: Andrzej Udalski <udalski(a)astrouw.edu.pl> Date (v1): Fri, 8 Oct 1999 16:33:32 GMT (33kb) Date (revised v2): Sun, 10 Oct 1999 11:58:20 GMT (33kb) Date (revised v3): Fri, 14 Jan 2000 15:35:00 GMT (36kb) The Optical Gravitational Lensing Experiment. Red Clump Stars as a Distance Indicator Authors: A. Udalski Comments: 11 pages. Latex+psfig. Accepted for publictation in ApJ Letters. Major revision: 30% larger sample of Hipparcos red giants with spectroscopic metallicities and extended photometry of the LMC field red clump stars (9 lines-of-sight). Due to journal space limitation, sections on comparison of the LMC red clump distance modulus with previous determinations and relations between the color indices and metallicity removed from this version We present relation of the mean I-band brightness of red clump stars on metallicity. Red clump stars were proposed to be a very attractive standard candle for distance determination. The calibration is based on 284 nearby red giant stars whose high quality spectra allowed to determine accurate individual metal abundances. High quality parallaxes (\sigma_\pi / \pi < 10%) and photometry of these very bright stars come from Hipparcos measurements. Metallicity of the sample covers a large range: -0.6<[Fe/H]<+0.2 dex. We find a weak dependence of the mean I-band brightness on metallicity (about 0.13 mag/dex). What is more important, the range of metallicity of the Hipparcos sample partially overlaps with metallicity of field giants in the LMC, thus making it possible to determine the distance to the LMC by almost direct comparison of brightness of the local Hipparcos red clump giants with that of LMC stars. Photometry of field red clump giants in nine low extinction fields of the LMC halo collected during the OGLE-II microlensing survey compared with the Hipparcos red clump stars data yields the distance modulus to the LMC: (m-M)_LMC=18.24+/-0.08 mag. ------------------------------------------------------ Astrophysics, abstract astro-ph/0010151 From: Andrzej Udalski <udalski(a)astrouw.edu.pl> Date: Sat, 7 Oct 2000 09:34:13 GMT (161kb) The Optical Gravitational Lensing Experiment. Stellar Distance Indicators in the Magellanic Clouds and Constraints on the Magellanic Cloud Distance Scale Authors: A. Udalski Comments: 26 pages, 8 figures (3 in 'jpg'format), LaTex Journal-ref: Acta Astronomica, 50, 279 BVI photometry of the Magellanic Clouds collected during the OGLE-II microlensing experiment makes it possible to study in detail photometric properties of the "major" stellar distance indicators in the Magellanic Clouds. In addition to Cepheids, RR Lyr and red clump stars, which photometry was presented in the earlier OGLE papers, we present the so far most accurate determination of brightness of the tip of the red giant branch in the LMC and SMC. We analyze the ratios of brightness of all four distance indicators in the LMC and SMC. Additionally, we include in our analysis, when possible, photometric data of the distance indicators in the metal poor Carina dwarf galaxy for which photometry was also collected during the OGLE-II experiment. The analysis is largely differential, free from zero point and extinction uncertainties. The main conclusion is that the distance scales resulting from all four stellar distance indicators are fully consistent with each other. Therefore the distance scale problem is not a problem resulting from different distances yielded by distance indicators, but rather a problem of the proper zero point of this common distance scale. All four stellar distance indicators have to be treated as an ensemble, and any determination of the zero point for one of them must predict reasonable luminosities of the others. This puts strong constraints on many proposed calibrations of distance indicators. For example, very bright calibrations of Cepheids or RR Lyr can practically be ruled out.

Cze�� wszysce, Dzisiaj robili�my rozmawianie informalne mi�dzy kilka ludzie kosmologyczne lub sympatyczne w CAMKu-Warsawie. Pami�tajcie �e ta lista mejla ma archiv publiczne, i lista jest dla ca�a dyskusja o badaniu kosmologia w Polsce (i oczywi�cie, morzecie zaprasa� inne kosmology dla subscribe o lista): http://www.astro.uni.torun.pl/sympa/cosmo-pl/ Bohdan m�wi� o kilka astronomy w Warszawie jak� robi� badanie bardzo interesuj�ce dla nasz, i kilka zdania o komunikacja mi�dzy astronome w samo miasto... Bohdan: prosz� pisa� jak mowi�isz o lista! (mailto:cosmo-pl@astro.uni.torun.pl) Pozdrawiam Boud PS: Przepraszam dla odmian przypadk�w jak� niedobre... ;)
