A companion galaxy to the poststarburst quasar UN J1025-0040.

Abstract (from CDS):

UN J1025-0040 is a quasar at z=0.6344 that shows an extremely bright post starburst population of age ∼400 Myr (Brotherton et al.). Images of UN J1025-0040 show a nearly stellar object 4".2 south-southwest of the quasar. We present imaging and spectroscopy that confirm that this object is a companion galaxy at redshift z=0.6341. We estimate an age of ∼800 Myr for the dominant stellar population in the companion. The companion appears to be interacting with the quasar host galaxy, and this interaction may have triggered both the starburst and the quasar activity in UN J1025-0040.
