Fossil groups in the Sloan Digital Sky Survey.

SANTOS W.A., MENDES DE OLIVEIRA C. and SODRE L.Jr

Abstract (from CDS):

A search for fossil groups in the Sloan Digital Sky Survey was performed using virtual observatory tools. A cross-match of the positions of all SDSS luminous red galaxies (with r<19 and measured spectroscopic redshifts) with sources in the ROSAT All-Sky Survey catalog resulted in a list of elliptical galaxies with extended X-ray emission (with a galaxy/ROSAT-source distance of less than 0.5' in all cases). A search for neighbors of the selected elliptical galaxies within a radius of 0.5 h–170 Mpc was conducted, taking into account the r-band magnitudes and spectroscopic or photometric redshifts of all objects within this area, leading to a sample of 34 candidate fossil groups. Considering this sample, the estimated space density of fossil systems is n=(1.0±0.6)x10–6 h350Mpc–3.
