Query: Constraints from Galaxy-AGN Clustering on the Correlation between Galaxy
  and Black Hole Mass at Redshifts 2<Z<3   We use the clustering of galaxies around distant active-galactic nuclei to
derive an estimate of the relationship between galaxy and black hole mass that
obtained during the ancient quasar epoch, at redshifts 2 <~ z <~ 3, when giant
black holes accreted much of their mass. Neither the mean relationship nor its
scatter differs significantly from what is observed in the local universe, at
least over the ranges of apparent magnitude (16 <~ G_AB <~ 26) and black-hole
mass (10^6 <~ M_BH/M_sun <~ 10^10.5) that we are able to probe.
