Does environment affect the star formation histories of early-type galaxies?
Ignacio Ferreras, Anna Pasquali, Ben Rogers
Differences in the stellar populations of galaxies can be used to quantify the effect of environment on the star formation history. We target a sample of early-type galaxies from t…
The Role of Environment on the Formation of Early-Type Galaxies
Ben Rogers, Ignacio Ferreras, Anna Pasquali +3
(Abridged) We present a detailed study of the stellar populations of a volume-limited sample of early-type galaxies from SDSS, across a range of environments -- defined as the mass…
Star formation and nuclear activity in close pairs of early-type galaxies
Ben Rogers, Ignacio Ferreras, Sugata Kaviraj +2
We extract from the Sloan Digital Sky Survey a sample of 347 systems involving early type galaxies separated by less than 30 kpc, in projection, and 500 km/s in radial velocity. Th…
