Under the Microscope: Galaxy Centres with OASIS
Early-type galaxies are thought to be among the oldest known stellar systems, and as such have experienced the full diversity of evolutionary mechanisms at work in the universe. They are crucial laboratories for understanding how galaxies form and evolve from early epochs until the present day. A key aspect of unlocking their fossil evidence is by studying the dynamics of stars and gas, and characterising the stellar populations. To this end, the SAURON survey has undertaken a study of 72 representative nearby early-type galaxies and spiral bulges using the SAURON integral field spectrograph at the WHT. Follow-up survey is being continued with OASIS at the WHT, with the aim of completing all E/S0s of the SAURON survey by spring 2005. Here we give an overview of this follow-up survey, and future prospects for using OASIS in this field.
