This Friday: When, where: 14.00 Fri 8.10.2010, @KRA. Topic: cosmology group web pages. i'll try to set up a switch so that people with laptops can edit simultaneously, but anybody is still welcome to participate without a laptop. Just by seeing people edit "live" may help you get the basic idea. At 15.00, following the wiki workshop and a short break, there'll be a cosmic topology workshop. pozdr boud From boud w astro.uni.torun.pl Mon Oct 11 10:30:30 2010 From: boud w astro.uni.torun.pl (Boud Roukema) Date: Mon, 11 Oct 2010 10:30:30 +0200 (CEST) Subject: [Cosmo-torun] arXiv:1010.1634 neural-network removal of WMAP foregrounds Message-ID: hi cosmo-torun, Foreground removal from WMAP 5yr temperature maps using an MLP neural network Authors: H. U. Norgaard - Nielsen http://arxiv.org/abs/1010.1634 This looks cool! i've just read it very briefly... My initial understanding is that it's like an ILC map but without the arbitrary definition of "regions". pozdr boud From boud w astro.uni.torun.pl Mon Oct 25 16:48:57 2010 From: boud w astro.uni.torun.pl (Boud Roukema) Date: Mon, 25 Oct 2010 16:48:57 +0200 (CEST) Subject: [Cosmo-torun] highest spectroscopically confirmed redshift: z = 8.6 Lehnert et al. 1010.4312 Message-ID: hi everyone, We're still a long way from galaxy/qso redshifts of 20 to 30, but we're getting towards 10: Spectroscopic confirmation of a galaxy at redshift z=8.6 Lehnert et al. http://arxiv.org/abs/1010.4312 By comparing to other high z galaxies, the stellar age is suggested to be in the range 0.01 to 0.1 Gyr. pozdr boud
