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

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

hi everyone, Cosmo workshop! 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
