This is the fifth paper in a series of investigations of the clustering
properties of luminous, broad-emission line active galactic nuclei (AGN)
identified in the ROSAT All-Sky Survey (RASS) and Sloan Digital Sky Survey
(SDSS). In this work we measure the cross-correlation function (CCF) between
RASS/SDSS DR14 AGN with the SDSS CMASS galaxy sample at 0.44<z<0.64. We apply
halo occupation distribution (HOD) modeling to the CCF along with the
auto-correlation function of the CMASS galaxies. We find that X-ray and
optically-selected AGN at 0.44<z<0.64 reside in statistically identical halos
with a typical dark matter halo mass of MDMHtyp,AGNββΌ1012.7hβ1Mββ. The acceptable HOD parameter space for these
two broad-line AGN samples have only statistically marginal differences caused
by small deviations of the CCFs in the 1-halo dominated regime on small scales.
In contrast to optically-selected AGN, the X-ray AGN sample may contain a
larger population of satellites at MDMHββΌ1013hβ1Mββ. We compare our measurements in this work with
our earlier studies at lower independent redshift ranges, spanning a look-back
time of 6 Gyr. The comparison over this wider redshift range of 0.07<z<0.64
reveals: (i) no significant difference between the typical DMH masses of X-ray
and optically-selected AGN, (ii) weak positive clustering dependencies of
MDMHtyp,AGNβ with LXβ and MBHβ, (iii) no significant
dependence of MDMHtyp,AGNβ on Eddington ratio, and (iv) the same
DMH masses host more massive accreting black holes at high redshift than at low
redshifts.Comment: 23 pages, 16 figures, 3 tables, accepted for publication in Ap
