Abstract

Abstract : Much progress has been made in recent years towards understanding how early-type galaxies (ETGs) form and evolve. SAURON (Bacon et al . 2001) integral-field spectroscopy from the ATLAS3D survey (Cappellari et al . 2011) has suggested that less massive ETGs are linked directly to spirals, whereas the most massive objects appear to form from a series of merging and accretion events (Cappellari et al . 2013). However, the ATLAS3D data typically only extends to about one half-light radius (or effective radius, Re ), making it unclear if this picture is truly complete.
