Kim Nilsson is a former PhD student at DARK and she finished in 2007. She is now working as a postdoc at The Max-Planck-Institute for Astronomy in Heidelberg, Germany. In April she will start working at ESO in München as a "Hubble Astronomer".

Thursday the 12th March Kim Nilsson will give a talk in the lounge at 14:00. The title of the talk is "Evolution in the properties of Lyman-alpha emitters between z ~ 3 and z ~ 2".

Abstract:

I will in this talk present the first results from the to date largest survey for Lyman-alpha emitters at z ~ 2. The data, taken with the WFI instrument on the ESO2.2m/MPG telescope, revealed 170 candidate Lyman-alpha emitters over an area of roughly 0.2 sq.degrees. When comparing the properties of this sample with those of z ~ 3 Lyman-alpha emitters we found several pieces of evidence of evolution in this type of galaxy; including a higher fraction of AGN, redder colours and in general smaller equivalent widths of the Lyman-alpha line. I will present all of these results, and show the very latest results of the SED fitting of the candidates.
