Atlas3D and the assembly of early-type galaxies

Paolo Serra, ASTRON Dwigeloo

I will discuss early results of the Atlas3D project. This consists of a multi wavelength survey of a large, volume-limited sample of nearby early-type galaxies, and of models and simulations of galaxy formation developed to interpret the observations. The project includes integral-field optical spectroscopy, optical imaging, molecular gas and neutral hydrogen observations of the galaxies in the sample. I will give a flavour of the project as a whole, and focus on the neutral hydrogen properties of early-type galaxies as a function of galaxy environment.
