Description
After a presentation of the new integral field spectrograph MUSE for the VLT and its first results, I will detail the observations performed on the well known Hubble Deep Field South. They are today the deepest spectroscopic survey ever achieved in optical spectroscopy. It has provided a wealth of new informations in the field of high and intermediate redshift galaxies. I will present the discovery of new high redshift Lyman alpha emitters beyond the limiting magnitude of Hubble and the unbiquitous presence of extended Lyman alpha halos around these galaxies and discuss their implication for galaxy evolution.
