A study of six low-redshift quasar pairs.
FARINA E.P., FALOMO R. and TREVES A.
Abstract (from CDS):
The dynamical properties of six Sloan Digital Sky Survey quasar pairs at z ≤ 0.8 are investigated. The pairs have proper transverse separation R⊥ ≤ 500 kpc, and velocity difference along the line of sight ΔVr ≤ 500 km/s. If they are bound systems their dynamical mass can be evaluated and compared with that of host galaxies. Evidence is found of an excess of the former mass with respect to the latter. This suggests that these quasar pairs are hosted by galaxies with massive dark haloes or that they reside in a group/cluster of galaxies.
