Abstract:
We present a dynamical analysis of the galaxy cluster Abell 1942 based
on a set of 128 velocities obtained at the European Southern
Observatory. Data on individual galaxies are presented and the
accuracy of the determined velocities as some properties of the
cluster are discussed. We have also made use of publicly available
Chandra X-ray data.
Description:
The Abell 1942 cluster of galaxies is within the area observed by the
Sloan Digital Sky Survey (SDSS). In this paper we adopt the
photometric data from its Data Release 6.
The A1942 spectra used in this paper have been obtained with the 3.60m
telescope at ESO-La Silla (Chile) in two runs during a total of ten
half-nights from 5 to 10 June 2005 and 30 April to 3 May 2006 (with 4
cloudy nights).
