Bayesian surface photometry analysis for early-type galaxies
D. H. Stalder, Reinaldo R. de Carvalho, Martin D. Weinberg +4
We explore the application of Bayesian image analysis to infer the properties of an SDSS early-type galaxy sample including AGN. We use GALPHAT (Yoon et al. 2010) with a Bayes-fact…
Systematic variation of central mass density slope in early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano +3
We study the total density distribution in the central regions ( effective radius, ) of early-type galaxies (ETGs), using data from the SPIDER survey. We model ea…
Systematic variations of central mass density slopes in early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano +3
We study the total density distribution in the central regions (~ 1 effective radius, ) of early-type galaxies (ETGs), using data from SPIDER and . Our analysi…
SPIDER - VI. The Central Dark Matter Content of Luminous Early-Type Galaxies: Benchmark Correlations with Mass, Structural Parameters and Environment
C. Tortora, F. La Barbera, N. R. Napolitano +2
We analyze the central dark-matter (DM) content of \sim 4,500 massive (M* \gsim 10^{10} Msun), low-redshift (z<0.1), early-type galaxies (ETGs), with high-quality ugrizYJHK photome…
On The Nature of Fossil Galaxy Groups
F. La Barbera, R. R. de Carvalho, I. G. de la Rosa +3
We present a new sample of 25 fossil groups (FGs) at z < 0.1, along with a control sample of seventeen bright ellipticals located in non-fossil systems. Both the global properties…
NoSOCS in SDSS. I. Sample Definition and Comparison of Mass Estimates
P. A. A. Lopes, R. R. de Carvalho, J. L. Kohl-Moreira +1
We use Sloan Digital Sky Survey (SDSS) data to investigate galaxy cluster properties of systems first detected within DPOSS. With the high quality photometry of SDSS we derived new…
