A photometric and kinematic study of AWM 7.

KORANYI D.M., GELLER M.J., MOHR J.J. and WEGNER G.

Abstract (from CDS):

We have measured redshifts and Kron-Cousins R-band magnitudes for a sample of galaxies in the poor cluster AWM 7. We have measured redshifts for 172 galaxies; 106 of these are cluster members. We determine the luminosity function (LF) from a photometric survey of the central 1.2x1.2 h–1 Mpc. The LF has a bump at the bright end and a faint-end slope of α = -1.37±0.16, populated almost exclusively by absorption-line galaxies. The cluster velocity dispersion is lower in the core (∼530 km.s–1) than at the outskirts (∼680 km.s–1), consistent with the cooling flow seen in the X-ray. The cold core extends ∼150 h–1 kpc from the cluster center. The Kron-Cousins R-band mass-to-light ratio of the system is 650 ± 170 h M☉/L☉, substantially lower than previous optical determinations, but consistent with most previous X-ray determinations. We adopt H0 = 100 h km.s–1.Mpc–1 throughout this paper; at the mean cluster redshift (5247±76 km.s–1), 1 h–1 Mpc subtends 65'.5.
