Query: Observations of quasar hosts with adaptive optics at Lick Observatory   We present near-infrared H-band observations of the hosts of three z~1
quasars from the Sloan Digital Sky Survey made with the adaptive optics system
at Lick Observatory. We derive a PSF for each quasar and model the host plus
quasar nucleus to obtain magnitudes and approximate scale sizes for the host
galaxies. We find our recovered host galaxies are similar to those found for
z~1 quasars observed with the Hubble Space Telescope. They also have, with one
interesting exception, black hole mass estimates from their bulge luminosities
which are consistent with those from emission-line widths. We thus demonstrate
that adaptive optics can be successfully used for the quantitative study of
quasar host galaxies, with the caveat that better PSF calibration will be
needed for studies of the hosts of significantly brighter or higher redshift
quasars with the Lick system.
