----- Forwarded message from NewsAlert ----- NEWSALERT: Friday, March 22, 2002 @ 1504 GMT --------------------------------------------------------------------- The latest news from Astronomy Now and Spaceflight Now [...] NEW EVIDENCE: EXPANSION OF UNIVERSE IS ACCELERATING --------------------------------------------------- A team of UK and Australian astronomers has discovered new, independent evidence that the expansion of the universe is accelerating. Their findings have just appeared in the Monthly Notices of the Royal Astronomical Society. 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. The ball is now firmly in the theorists court." http://spaceflightnow.com/news/n0203/22expansion/ [...] ----- End of forwarded message from NewsAlert ----- -- Andrzej Marecki

OCRA - mass function of haloes
by Boud Roukema 29 Mar '02

29 Mar '02

Hi everyone, Inoue & Nagashima have a paper http://de.arXiv.org/abs/astro-ph/0110503 about the mass function of dark matter haloes, in other words, the frequency of how many objects of different masses (high or low) form at a given epoch during the collapse of matter due to gravity. I think this could be an important paper for modelling what statistical constraints on Omega_m & Omega_Lambda (or eventually w_Q) could be obtained from OCRA. Boud

European Pdoc? (M Curie-Skl)
by Boud Roukema 21 Mar '02

21 Mar '02

Questionnaire for research institutions in Poland interested to host Marie Curie-Sk�odowska postdoctoral fellowships to be sent to ph3(a)npk.gov.pl Institution: Uniwersytet Mikolaja Kopernika Institute: Toru� Centre for Astronomy Address: ul. Gagarina, 11, PL-87-100, Toru� Homepage: http://www.astro.uni.torun.pl/sympa/ Contact person: Dr Boud Roukema Phone/fax: +48 56 611 3039/+48 56 611 3009 Email: boud(a)astro.uni.torun.pl Research field: observational cosmology Working languages: English, French, Polish Description of research topic/subject: The postdoctoral fellow would be expected to carry out original, independent research in any field of observational cosmology, and to stimulate discussion of observational cosmology among faculty and students. Fields presently being developed or likely to be developed at the Toru� Centre for Astronomy include constraints on local cosmological parameters such as the matter density parameter, the cosmological constant and the effective quintessence parameter, using public archival data; attempts to measure global parameters via topological lensing, using radio-loud AGNs, clusters and the cosmic microwave background; and galaxy formation and evolution. Candidates in other fields of observational cosmology are welcome to apply: excellence and originality of research will be the primary criteria for making a selection. >>>>>>>>>>>>>>>> cut here <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< [Comment to cosmo-torun group: This is an administrative request to see if we can get some money for a European postdoc. Andrzej M, Andrzej K and I thought it best to keep the subject open to any theme in observational cosmology. I think we have till Monday before Wydzia� Fizyka meets to discuss the proposals, so please make any comments, criticisms, complaints, suggestions quickly!]

Hello .. Przyjade na Wielkanoc do Polski i bede przez pewien czas w Toruniu. W zwiazku z tym chcialbym Wam opowiedziec o mojej pracy w Jodrell, ktora dotyczy ewolucji kosmologicznej AGN'ow. Chcialbym przedstawic swoje pierwsze wyniki i omowic obecne problemy w tym temacie. Udalo mi sie tez zbudowac model nieba radiowego na czestosci 30 GHz, czyli to co powinnismy widziec za pomoca OCRY. W Toruniu bede obecny przez tydzien tuz przed Swietami.. cheers MPG

Conference Announcement (fwd)
by Boud Roukema 08 Mar '02

08 Mar '02

An important topic! ---------- Forwarded message ---------- > Date: Thu, 07 Mar 2002 19:01:49 -0500 (EST) > From: Thomas Reiprich <thr4f(a)virginia.edu> > To: "Conference, Cooling Flows": ; > Subject: Conference Announcement Dear colleague, March 5, 2002 this is the First Announcement of the Conference on ******************************************************************** * * * The Riddle of Cooling Flows in Galaxies and Clusters of Galaxies * * * * which will take place at the * * * * Omni Hotel, Charlottesville, VA, USA * * from May 31 through June 4, 2003 * * * ******************************************************************** Note that future announcements will ONLY be sent to people who pre-registered through http://www.astro.virginia.edu/coolflow/preg.php Recent observations have significantly broadened our view on cooling flows in galaxies and clusters of galaxies. The wealth of new information through observations has led to a flourishing development in theoretical modelling. The purpose of this conference is to summarize relevant observational results at all wavelengths, to compare the predictions of models and simulations to these observations, and to assess the impact of processes in cluster cores on the application of galaxy clusters as cosmological probes. All further relevant information has been posted at the conference web page ******************************************* * http://www.astro.virginia.edu/coolflow/ * ******************************************* If you are potentially interested please take a short moment to fill in the pre-registration form to ensure receiving future announcements. We apologize if you received this Announcement more than once. This Announcement was originally sent on March 5 but due to a mailing problem a very large fraction of the recipients did not receive this mail. Sincerely, Thomas Reiprich If you don't have access to the WWW you may contact Thomas Reiprich by phone: +1-434-924-4904, fax: +1-434-924-3104, or snail mail: Department of Astronomy University of Virginia PO Box 3818 530 McCormick Road Charlottesville, VA 22903-0818 USA -- You can find my address at: http://www.reiprich.net/
