Galaxy Zoo: a sample of blue early-type galaxies at low redshift
(2009)
We report the discovery of a population of nearby, blue early-type galaxies with high star formation rates (0.5 < SFR < 50 M⊙ yr−1) . They are identified by their visual morphology as provided by Galaxy Zoo for Sloan Digital ...
Do moderate-luminosity active galactic nuclei suppress star formation?
(2009)
The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations and simulations of galaxy formation ...
