A quasar is observed at a redshift of z=1, which corresponds to a comoving radial distance of 3 Gpc. Its observed bolometric flux is 10^{-12} erg/cm^2/s. An interacting companion galaxy is seen 4 arcsec apart in projection.
What is the bolometric luminosity of the quasar, in solar luminosity units?
What is the projected linear separation from the companion galaxy, in kpc?
