CMB energy

Hi all, CMB photons are red-shifted due to Universe expansion -> this means that the whole CMB energy gets smaller... where does it go? pozdrawiam Jarek

Witam, Jak rozumiem, nasze propozycja dla dyskusji panelowej o temat kosmologii byli akceptowany dla Festiwału Nauki: http://adjani.astro.uni.torun.pl/cgi-bin/twiki/view/Cosmo/FestiwalNauki2004 Proszę do mąlego poprawki: Pisaliśmy że Michał Frąckowiak chce uczestniczyć, ale prawdziwie on nie chce uczestniczyć. Proszę usunuj swoj nazwa od listy uczestników na baz danych Festiwału. Pozdrawiam serdecznie Boud Roukema (Centrum Astronomii UMK)

festiwal nauki
by Boud Roukema 24 Feb '04

hi - i updated the Festiwal Nauki page: http://adjani.astro.uni.torun.pl/cgi-bin/twiki/view/Cosmo/FestiwalNauki2004 Please correct, update, modify... i guess it's now obvious why there was silly bureaucracy - there's money (150 zl) paid to official speakers (and if i understood the small print, "students" cannot be paid, though doktoranci are OK) - this is not a "grassroots" festival by scientists... Missing info: how much time do we have? One hour? Two hours? And is this time schedule definitely fixed? Staszek Krawczyk and A Strobel seem to be the official contacts so i'm cc-ing them here. boud

Cosmo parameters according to VSA
by Andrzej Marecki 20 Feb '04

20 Feb '04

Paper: astro-ph/0402466 Title: Cosmological parameter estimation using Very Small Array data out to l=1500 Authors: Rafael Rebolo, Richard A. Battye, Pedro Carreira, Kieran Cleary, et al. We estimate cosmological parameters using data obtained by the Very Small Array (VSA) in its extended configuration, in conjunction with a variety of other CMB data and external priors. Within the flat $\Lambda$CDM model, we find that the inclusion of high resolution data from the VSA modifies the limits on the cosmological parameters as compared to those suggested by WMAP alone, while still remaining compatible with their estimates.

Re: wewnetrzny grant UMK

hi everyone, Attached are two equivalent copies of the draft application (pdf to help a certain person who uses micro$oft ;) Any substantial comments, criticisms? (Or trivial ones?) Given that it's for pedagogical purposes, i haven't put anything about a specific "research project". i put my title as "dr" since i presume i don't officially have "hab" until the central committee confirms it. i can expect the bureaucrats may complain that the format is slightly changed, but that's their fault for using micro$oft. They're here to support us, we're not here to work for them doing trivia. pozd boud

wewnetrzny grant UMK
by Boud Roukema 18 Feb '04

hi Andrzej (Kus), Apparently we need to spend 5kPLN of an internal UMK grant money/application and decide by tomorrow? IMHO this would be best spent on improving the computing facilities in the student room in KRA. If formally speaking this should be for a research project, that's no problem - the whole existence of the internet means that students can get a taste of research and be motivated to study questions of which the answers are not yet known. As the students get to learn how to program, find theoretical information and observational data, and analyse it in ways they understand, they also will start contributing to research (hopefully). i meant to have a look at the computers with Roman before the new semester started, i didn't realise it had already started. i remember some students claiming not many of the terminals/computers were working properly, but i didn't get around to checking specifically. ** It could certainly not hurt to buy another computer, which we can put as cosmic topology research - or for Bartek and my dark matter projects - but which i can set up for secondary usage by the students who i'm sure can always use more cpu and disk space. ** Maybe also a DAT drive + a few dozen DAT tapes (to last several years) for backups so that all the students can have a decent amount of backed up disk space. KA&A seems to have more or less good student support but we clearly are pushing the limits with the larger numbers of students. pozd boud
