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* ...
Triggered star formation in the inner filament of Centaurus A
(2012-04-01)
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 ...
