Query: Predictions of Quasar Clustering: Redshift, Luminosity and Selection
  Dependence   We show that current clustering observations of quasars and luminous AGN can
be explained by a merger model augmented by feedback from outflows. Using
numerical simulations large enough to study clustering out to 25 comoving
h^{-1} Mpc, we calculate correlation functions, biases, and correlation lengths
as a function of AGN redshift and optical and X-ray luminosity. At optical
wavelengths, our results match a wide range of current observations and
generate predictions for future data sets. We reproduce the weak luminosity
dependence of clustering over the currently well-measured range, and predict a
much stronger dependence at higher luminosities. The increase in the amplitude
of binary quasar clustering observed in the Sloan Digital Sky Survey (SDSS) is
also reproduced and is predicted to occur at higher redshift, an effect that is
due to the one halo term in the correlation function. On the other hand, our
results do not match the rapid evolution of the correlation length observed in
the SDSS at z\simeq 3, a discrepancy that is at least partially due to
differences in the scales probed by our simulation versus this survey. In fact,
we show that changing the distances sampled from our simulations can produce
changes as large as 40% in the fitted correlation lengths. Finally, in the
X-ray, our simulations produce correlation lengths similar to that observed in
the Chandra Deep Field (CDF) North, but not the significantly larger
correlation length observed in the CDF South.
