The size evolution of passive galaxies : observations from the Wide-Field Camera 3 Early Release Science program
We present the size evolution of passively evolving galaxies at z 2 identified in Wide-Field Camera 3 imaging from the Early Release Science program. Our sample was constructed using an analog to the passive BzK galaxy ...
Triggered star formation in the inner filament of Centaurus A
We present recent Hubble Space Telescope observations of the inner filament of Centaurus A, using the new Wide Field Camera 3 (WFC3) F225W, F657N and F814W filters. We find a young stellar population near the south-west ...
A panchromatic catalog of early-type galaxies at intermediate redshift in the Hubble Space Telescope wide field camera 3 early release science field
In the first of a series of forthcoming publications, we present a panchromatic catalog of 102 visually selected early-type galaxies (ETGs) from observations in the Early Release Science (ERS) program with the Wide Field ...
Minor-merger-driven growth of early-type galaxies over the last 8 billion years
(Cambridge University Press, 2011-09)
We summarise recent progress in understanding the star formation activity in early-type galaxies (ETGs), using recent studies that leverage photometry in the rest-frame ultraviolet (UV) wavelengths. While classically thought ...
Anatomy of a post-starburst minor merger : A multi-wavelength WFC3 study of NGC 4150
We present a spatially resolved near-UV/optical study, using the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope, of NGC 4150, a sub-L , early-type galaxy (ETG) of around 6 × 10 M , which has been observed ...
