Abstract:
We study the internal dynamics of the rich galaxy cluster ABGC 209 on
the basis of new spectroscopic and photometric data. The distribution
in redshift shows that ABCG 209 is a well isolated peak of 112
detected member galaxies at z=0.209, characterised by a high value of
the line-of-sight velocity dispersion, sigma_v_=1250-1400km/s, on
the whole observed area (1h^-1^Mpc from the cluster center), that leads
to a virial mass of M=1.6-2.2x10^15^h^-1^M_sun_ within the virial
radius, assuming the dynamical equilibrium.
The data were collected at the ESO New Technology Telescope (NTT) with
the ESO Multi Mode Instrument (EMMI) in October 2001.
