witam wszystkim, Jean-Pierre Luminet might come to visit us in January. i think that this would be a great chance for people here to have some general discussion on the state of research in cosmic topology with someone other than me. :) http://arxiv.org/find/astro-ph/1/au:luminet/0/1/0/all/0/1 pozdr boud

Porozumienie "Kosmologia i czastki elementarne" (fwd)
by Boud Roukema 15 Oct '06

hi cosmo-torun, We as the CA-UMK group of the cosmo-pp network need to choose, by this weekend (15.10.06), between Mariusz Dąbrowski and Marek Zrałek as "przewodniczący" of the cosmo-pp network. The vote seems to be confidential, though each group presumably has its own way of deciding. i suggest informal discussion by whatever means (email/face-to-face/...) and attempts to get informal consensus - consensus probably better *not* on public lists/twiki if it's about personal stuff of the two candidates, but IMHO it can be public if it's a meta-level question (e.g. should we ask questions to the two candidates?) i suggest the following procedure (since we won't necessarily get consensus): * everyone who wants to "vote" email me his/her vote before the deadline * i will publish the names of the people who vote and which candidate has the majority - if it's 50:50 i'll toss a coin. If someone wants a more formal or structured process, then please propose it. Both candidates seem fine to me, so i don't expect this to be terribly controversial, but as a matter of principle, i prefer it to be more participatory rather than less participatory. After all, in the long term this sort of thing does have an effect and jobs and cosmology funding. See http://arxiv.org: hep-ph, astro-ph, gr-qc for Mariusz' and Marek's scientific work. For their experience as moderators, i guess you need to look elsewhere. pozdr boud > ---------- Forwarded message ---------- > Date: Mon, 9 Oct 2006 14:45:44 +0200 (CEST) > From: Krzysztof Meissner... > To: Stefan Pokorski.. > Subject: Porozumienie "Kosmologia i czastki elementarne" > > Szanowni Panstwo, > > Zgodnie z decyzja wszystkich uczestnikow, `Porozumienie o > wspolpracy naukowej w dziedzinie badan teoretycznych "Czastki - > astrofizyka - kosmologia" ' ma posiadac strukture sieci tzn. miec > koordynatora i rade naukowa.

hi cosmo-torun, If nobody has any objections, i'll send the following email to the "Rozumienie" that Marek Zrałek is coordinating. Reminder: this is cosmologists/particle physicists organising a "pre-formal" network in Poland, which can later be joined to create a European network, in order to get research funding for cosmologyu/particle physics. At the moment it's only "informal" with the idea of waiting until a new ustawa comes through, but the cosmologists from the different institutes are writing sort of formally. We're asked to respond by tomorrow (sorry about not writing earlier) about "votes" (or proposals) for a head of the council and a coordinator - several people have proposed Stefan Pokorski as council head and Marek Zrałek as coordinator. You can see what they do (hep-ph - high-energy physics phenomenology) here: Marek: http://arxiv.org/find/hep-ph/1/au:+zralek/0/1/0/all/0/1 Stefan: http://arxiv.org/find/hep-ph/1/au:pokorski/0/1/0/all/0/1 i think their scientific track records speak for themselves. If noone objects by tomorrow, i'll post the text below to the (offlist) cc: list of the porozumienie. pozdr boud ---------------------------------------------------------------------- Porozumienie "Kosmologia i czastki elementarne" Drogie Koleżanki i drodzy Koledzy, Proponuję w imeniu Centrum Astronomicznego Uniwersytetu Mikołaja Kopernika Prof. Marka Zrałka na stanowisko Przewodniczacego Rady i Prof. Stefana Pokorskiego na stanowisko Koordynatora. Serdecznie pozdrawiam wszystkich uczestnikow Porozumienia Boud Roukema, CA-UMK ----------------------------------------------------------------------

draft title/abstract for seminar
by Boud Roukema 04 Oct '06

04 Oct '06

witam cosmo-torun, Andrzej Kus mi prosił zrobić seminarium poniedziałek 9.10.2006. Jeśli ktoś chce sugerować poprawki, proszę mów. Abstrakt jest raczej długi, ale jest trudny zrobić krótkiejszy dla osoby nie znając temat... Oczywiście, będę też iść trochę na wyniki WMAP itd, ale nie widzę, że muszę to mówić w abstrakcie. pozdr boud Title 2006 Nobel prize: Cosmological black body and density perturbations Abstract The standard hot big bang model became widely accepted as a serious model in 1965 after the discovery of the 3 Kelvin primordial background radiation (CMB), but it was still regarded sceptically by many astronomers. During the 1980s and early 1990s, the model's prediction that the background radiation should have a nearly perfect Planckian black body spectrum was only weakly tested. The other untested prediction of the model was that the Universe is not perfectly uniform, it needed density perturbations which could gravitationally collapse to form clusters of galaxies and galaxies and stars. The COBE satellite, coordinated by Smoot, Mather and Wilkinson, revealed that the CMB black body was more perfect than any black body created artificially in Earth based laboratories. Moreover, in its map of the CMB, it detected 0.001% fluctuations in the temperature - revealing the density perturbations necessary to form galaxies. These results spectacularly confirmed two of the basic physical predictions of the hot big bang model.

ESO-ESA working group on fundamental cosmology: report
by Boud Roukema 03 Oct '06

03 Oct '06

http://www.stecf.org/coordination/esa_eso/wg.php?working_group=cosmology ESA-ESO WG on Fundamental Cosmology Working Group Members: George Efstathiou John Ellis Bruno Leibundgut Simon Lilly Yannick Mellier John Peacock (chair) Peter Schneider (co-chair) Abstract of final report In September 2003, the executives of ESO and ESA agreed to establish a number of working groups to explore possible synergies between these two major European astronomical institutions on key scientific issues. The first two working group reports (on Extrasolar Planets and the Herschel--ALMA Synergies) were released in 2005 and 2006, and this third report covers the area of Fundamental Cosmology. The Working Group's mandate was to concentrate on fundamental issues in cosmology, as exemplified by the following questions: * What are the essential questions in fundamental cosmology? * Which of these questions can be tackled, perhaps exclusively, with astronomical techniques? * What are the appropriate methods with which these key questions can be answered? * Which of these methods appear promising for realization within Europe, or with strong European participation, over the next ~15 years? * Which of these methods has a broad range of applications and a high degree of versatility even outside the field of fundamental cosmology? >From the critical point of view of synergy between ESA and ESO, one major resulting recommendation concerns the provision of new generations of imaging survey, where the image quality and near-IR sensitivity that can be attained only in space are naturally matched by ground-based imaging and spectroscopy to yield massive datasets with well-understood photometric redshifts (photo-z's). Such information is essential for a range of new cosmological tests using gravitational lensing, large-scale structure, clusters of galaxies, and supernovae. All these methods can in principle deliver high accuracy, but a multiplicity of approaches is essential in order that potential systematics can be diagnosed -- or the possible need for new physics revealed. Great scope in future cosmology also exists for ELT studies of the intergalactic medium and space-based studies of the CMB and gravitational waves; here the synergy is less direct, but these areas will remain of the highest mutual interest to the agencies. All these recommended facilities will produce vast datasets of general applicability, which will have a tremendous impact on broad areas of astronomy.

hi everyone, There's a media thread here for the Smoot/Mather Nobel prize: http://cosmo.torun.pl/pipermail/cosmo-media/2006-October/thread.html i don't want to spam everyone, so please just update the twiki: http://cosmo.torun.pl/cgi-bin/twiki/view/Cosmo/MediaNobelSmootMather or subscribe to and respond on cosmo-media. A tv crew will be here (KRA) around 15.30. pozdr boud
