The SDSS-UKIDSS Fundamental Plane of Early-type Galaxies
F. La Barbera, G. Busarello, P. Merluzzi +3
We derive the Fundamental Plane (FP) relation for a sample of 1430 early-type galaxies in the optical (r band) and the near-infrared (K band), by combining SDSS and UKIDSS data. Wi…
2DPHOT: A Multi-purpose Environment for the Two-dimensional Analysis of Wide-field Images
F. La Barbera, R. R. de Carvalho, J. L. Kohl-Moreira +5
We describe 2DPHOT, a general purpose analysis environment for source detection and analysis in deep wide-field images. 2DPHOT is an automated tool to obtain both integrated and su…
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…
On the Invariant Distribution of Galaxies in the re--mie plane out to z = 0.64
F. La Barbera, G. Busarello, P. Merluzzi +2
We study the evolution of the relation between half-light (effective) radius, r_e, and mean surface brightness, mi_e, known as Kormendy relation, out to redshift z=0.64 in V-band r…
Age, Metallicity and Star Formation History of Cluster Galaxies at z~0.3 F
P. Merluzzi, F. La Barbera, M. Massarotti +2
We investigate the color-magnitude distribution in the rich cluster AC 118 at z=0.31. The sample is selected by the photometric redshift technique, allowing to study a wide range o…
Optical (VRI) Photometry in the Field of the Galaxy Cluster AC 118 at z=0.31
G. Busarello, Merluzzi, F. La Barbera +2
We present new photometric V-, R- and I-band data for the rich galaxy cluster AC 118 at z=0.31. The new photometry covers an area of 8.6x8.6 arcmin, corresponding to 2.9$\times…
Optical and Near-Infrared Structural Properties of Cluster Galaxies at
F. La Barbera, G. Busarello, P. Merluzzi +2
Structural parameters (half-light radius , mean effective surface brightness , and Sersic index n) are derived for a sample of galaxies in the rich cluster AC 118 at z=…
