The environmental dependence of the structure of galactic discs in STAGES S0 galaxies: Implications for S0 formation

Maltby, David T; Aragon-Salamanca, A; Gray, M E; Hoyos, Carlos; Wolf, Christian; Jogee, Shardha; Bohm, A


We present an analysis of V-band radial surface brightness μ(r) profiles for S0 galaxies in different environments using Hubble Space Telescope/Advanced Camera for Surveys imaging and data from the Space Telescope A901/2 Galaxy Evolution Survey. Using a large sample of ∼280 field and cluster S0s, we find that in both environments, ∼25 per cent have a pure exponential disc (type I) and ∼50 per cent exhibit an up-bending disc break (antitruncation, type III). However, we find hardly any...[Show more]
