Title: A Redshift Survey of the Nearby Galaxy Cluster Abell 2199: Comparison of the Spatial and Kinematic Distributions of Galaxies with the Intracluster Medium,
Abstract: We present the results from an extensive spectroscopic survey of the central
region of the nearby galaxy cluster Abell 2199 at $z=0.03$. By combining 775
new redshifts from the MMT/Hectospec observations with the data in the
literature, we construct a large sample of 1624 galaxies with measured
redshifts at $R<30^\prime$, which results in high spectroscopic completeness at
$r_{\rm petro,0}<20.5$ (77%). We use these data to study the kinematics and
clustering of galaxies focusing on the comparison with those of the
intracluster medium (ICM) from Suzaku X-ray observations. We identify 406
member galaxies of A2199 at $R<30^\prime$ using the caustic technique. The
velocity dispersion profile of cluster members appears smoothly connected to
the stellar velocity dispersion profile of the cD galaxy. The luminosity
function is well fitted with a Schechter function at $M_r<-15$. The radial
velocities of cluster galaxies generally agree well with those of the ICM, but
there are some regions where the velocity difference between the two is about a
few hundred kilometer per second. The cluster galaxies show a hint of global
rotation at $R<5^\prime$ with $v_{\rm rot}=300{-}600\,\textrm{km s}^{-1}$, but
the ICM in the same region do not show such rotation. We apply a
friends-of-friends algorithm to the cluster galaxy sample at $R<60^\prime$ and
identify 32 group candidates, and examine the spatial correlation between the
galaxy groups and X-ray emission. This extensive survey in the central region
of A2199 provides an important basis for future studies of interplay among the
galaxies, the ICM and the dark matter in the cluster.
