Satellite Galaxies and Fossil Groups in the Millennium Simulation
L. V. Sales, J. F. Navarro, D. G. Lambas +2
We use a semianalytic galaxy catalogue constructed from the Millennium Simulation to study the satellites of isolated galaxies in the LCDM cosmogony. This sample (~80,000$ bright p…
The distant red galaxy neighbour population of 1 < z < 2 QSOs and optically obscured sources
Carlos G. Bornancini, Diego Garcia Lambas
We study the Distant Red Galaxy (DRG, J-K_s > 2.3) neighbour population of Quasi Stellar Objects (QSOs) selected from the Sloan Digital Sky Survey (SDSS) in the redshift range 1 <…
AGNs and galaxy interactions
M. Sol Alonso, Diego G. Lambas, Patricia Tissera +1
We perform a statistical analysis of AGN host characteristics and nuclear activity for AGNs in pairs and without companions. Our study concerns a sample of AGNs derived from the SD…
