  • We report the discovery of a transparent sightline at projected distances of {\rho} < 20 kpc to an interacting pair of mature galaxies at z = 0.12. The sightline of the UV-bright quasar PG1522+101 at z = 1.328 passes at {\rho} = 11.5 kpc from the higher-mass galaxy (M_* = 10^10.6 M_Sun) and {\rho} = 20.4 kpc from the lower-mass one (M_* = 10^10.0 M_Sun). The two galaxies are separated by 9 kpc in projected distance and 30 km/s in line-of-sight velocity. Deep optical images reveal tidal features… CONTINUE READING
