Abstract:
We report the results of a spectroscopic survey of faint galaxies in
the regions surrounding Hickson compact groups. Our sample is composed
of 17 groups within 9000km/s. The spectra were taken at the prime
focus of the Tololo 4m telescope, using the ARGUS fiber-fed
spectrograph. From these observations, redshifts were determined for
the faint galaxies previously identified by de Carvalho, Ribeiro &
Zepf (1994ApJS...93...47D 1994ApJS...93...47D) in the surroundings of the groups.
Statistical methods were applied to the resultant catalog in order to
determine the kinematical structure of each group. This analysis
confirms the idea that the Hickson sample of compact groups contains a
wide variety of projection and dynamical configurations. Our results
demonstrate the necessity of new spectroscopic surveys around compact
groups in order to assess their complete velocity distribution.
