The Voronoi Tessellation cluster finder in 2+1 dimensions
Marcelle Soares-Santos, Reinaldo R. de Carvalho, James Annis +6
We present a detailed description of the Voronoi Tessellation (VT) cluster finder algorithm in 2+1 dimensions, which improves on past implementations of this technique. The need fo…
Galaxy evolution as a function of environment and luminosity
A. Mercurio, C. P. Haines, A. Gargiulo +3
We present an analysis of star formation and nuclear activity of about 28000 galaxies in a volume-limited sample taken from SDSS DR4 low-redshift catalogue (LRC) taken from the New…
SPIDER - IV. Optical and NIR color gradients in Early-type galaxies: New Insights into Correlations with Galaxy Properties
F. La Barbera, R. R. de Carvalho, I. G. de la Rosa +3
We present an analysis of stellar population gradients in 4,546 Early-Type Galaxies with photometry in along with optical spectroscopy. A new approach is described which…
SPIDER - III. Environmental Dependence of the Fundamental Plane of Early-type Galaxies
F. La Barbera, P. A. A. Lopes, R. R. de Carvalho +2
We analyse the Fundamental Plane (FP) relation of early-type galaxies (ETGs) in the optical (griz) and ETGs in the Near-Infrared (YJHK) wavebands, forming an optic…
