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 ...
Tidal dwarf galaxies in the nearby Universe
(2012-01-01)
We present a statistical observational study of the tidal dwarf (TD) population in the nearby Universe by exploiting a large, homogeneous catalogue of galaxy mergers compiled from the Sloan Digital Sky Survey. 95percent ...
