Shapley Optical Survey. I: Luminosity Functions in the Supercluster Environment
A. Mercurio, P. Merluzzi, C. P. Haines +6
We present the Shapley Optical Survey, a photometric study covering a 2 deg^2 region of the Shapley Supercluster core at z ~ 0.05 in two bands (B and R). The galaxy sample is compl…
Detection of Radial Surface Brightness Fluctuation and Color Gradients in elliptical galaxies with ACS
Michele Cantiello, John P. Blakeslee, Gabriella Raimondo +3
We study surface brightness fluctuations (SBF) in a sample of 8 elliptical galaxies using Advanced Camera for Surveys (ACS) Wide Field Channel (WFC) data drawn from the Hubble Spac…
Color Gradients in Early-type Galaxies: Dependence on Environment and Redshift
F. La Barbera, R. R. de Carvalho, R. Gal +4
Color gradients in early-type galaxies contain valuable clues about their formation and evolutionary histories and mechanisms. We examine color gradients in 1,700 early-type galaxi…
VST - VLT Survey Telescope Integration Status
C. Belfiore, M. Brescia, M. Capaccioli +20
The VLT Survey Telescope (VST) is a 2.6m aperture, wide field, UV to I facility, to be installed at the European Southern Observatory (ESO) on the Cerro Paranal Chile. VST was prim…
New insights into the structure of early-type galaxies: the Photometric Plane at z~0.3
F. La Barbera, G. Covone, G. Busarello +4
We study the Photometric Plane (PHP), namely the relation between the effective radius re, the mean surface brightness within that radius <mi>e, and the Sersic index n, in optical…
