Interacting galaxies: co-rotating and counter-rotating systems with tidal tails
Valeria Mesa, Fernanda Duplancic, Sol Alonso +2
We analyse interacting galaxy pairs with evidence of tidal features in the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7). The pairs were selected within by requiring a…
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…
