Newborn spheroids at high redshift : When and how did the dominant, old stars in today's massive galaxies form?
We study ~330 massive (M > 10M), newborn spheroidal galaxies (SGs) around the epoch of peak star formation (1 <z <3) to explore the high-redshift origin of SGs and gain insight into when and how the old stellar populations ...
A WFC3 study of globular clusters in NGC 4150 : An early-type minor merger
We combine near-ultraviolet (NUV; 2250 Å) and optical (U, B, V, I) imaging from the Wide Field Camera 3 (WFC3), on-board the Hubble Space Telescope (HST), to study the globular cluster (GC) population in NGC 4150, a sub-L* ...
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 ...
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 ...
The Hubble Space Telescope wide field camera 3 early release science data : Panchromatic faint object counts for 0.2-2 μm wavelength
We describe the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) Early Release Science (ERS) observations in the Great Observatories Origins Deep Survey (GOODS) South field. The new WFC3 ERS data provide calibrated, ...
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 ...
