Low X-Ray Luminosity Galaxy Clusters. II. Optical properties and morphological content at 0.18 < z < 0.70
José Luis Nilo Castellón, M. Victoria Alonso, Diego García Lambas +4
This is the second of a series of papers on low X-ray luminosity galaxy clusters, in which we present the , and photometry obtained with GMOS-IMAGE…
On the relation between Seyfert 2 accretion rate and environment at z < 0.1
Georgina V. Coldwell, Sebastian Gurovich, Jorge Diaz Tello +2
We analyse different properties of the small scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the DR7-SDSS survey. We comp…
Calibration of semi-analytic models of galaxy formation using Particle Swarm Optimization
Andrés N. Ruiz, Sofía A. Cora, Nelson D. Padilla +8
We present a fast and accurate method to select an optimal set of parameters in semi-analytic models of galaxy formation and evolution (SAMs). Our approach compares the results of…
Clues on void evolution I: Large scale galaxy distributions around voids
L. Ceccarelli, D. Paz, M. Lares +2
We perform a statistical study focused on void environments. We examine galaxy density profiles around voids in the SDSS, finding a correlation between void--centric distance to th…
Galaxy triplets in Sloan Digital Sky Survey Data Release 7: II. A connection with compact groups?
Fernanda Duplancic, Ana Laura O'Mill, Diego G. Lambas +2
We analyse a sample of 71 triplets of luminous galaxies derived from the work of O'Mill et al. (2012). We compare the properties of triplets and their members with those of control…
Clues on void evolution II: Measuring density and velocity profiles on SDSS galaxy redshift space distortions
Dante Paz, Marcelo Lares, Laura Ceccarelli +2
Using the redshift-space distortions of void-galaxy cross-correlation function we analyse the dynamics of voids embedded in different environments. We compute the void-galaxy cross…
