The evolution of the star formation activity in galaxies and its dependence on environment
B. M. Poggianti, A. von der Linden, G. De Lucia +16
We study how the proportion of star-forming galaxies evolves between z=0.8 and z=0 as a function of galaxy environment, using the [OII] line in emission as a signature of ongoing s…
Discovery of a bright quasar without a massive host galaxy
Pierre Magain, Geraldine Letawe, Frederic Courbin +4
Quasars are thought to be powered by the infall of matter onto a supermassive black hole at the centre of massive galaxies. As the optical luminosity of quasars exceeds that of the…
EDisCS -- the ESO Distant Cluster Survey -- Sample Definition and Optical Photometry
S. D. M. White, D. I. Clowe, L. Simard +23
We present the ESO Distant Cluster Survey (EDisCS) a survey of 20 fields containing distant galaxy clusters with redshifts ranging from 0.4 to almost 1.0. Candidate clusters were c…
The Metallicity Distribution Function of Field Stars in M31's Bulge
Ata Sarajedini, Pascale Jablonka
We have used Hubble Space Telescope Wide Field Planetary Camera 2 observations to construct a color-magnitude diagram (CMD) for the bulge of M31 at a location ~1.6 kpc from the gal…
