A WFC3 study of globular clusters in NGC 4150 : An early-type minor merger
(2012-05-01)
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
(2012-04-10)
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 ...
