Galaxy Zoo : Dust lane early-type galaxies are tracers of recent, gas-rich minor mergers
(2012-06-01)
We present the second of two papers concerning the origin and evolution of local early-type galaxies exhibiting dust features. We use optical and radio data to examine the nature of active galactic nucleus (AGN) activity ...
Galaxy Zoo : Dust and molecular gas in early-type galaxies with prominent dust lanes
(2012-06-01)
We explore the properties of dust and associated molecular gas in 352 nearby (0.01 <z <0.07) early-type galaxies (ETGs) with prominent dust lanes, drawn from the Sloan Digital Sky Survey (SDSS). Two-thirds of these 'dusty ...
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 ...
A panchromatic catalog of early-type galaxies at intermediate redshift in the Hubble Space Telescope wide field camera 3 early release science field
(2012-03-01)
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 ...
