Abstract:
We present a combined X-ray and optical analysis of three bimodal
galaxy clusters selected as merging candidates at z∼0.1. These
targets are part of MUSIC (MUlti-Wavelength Sample of Interacting
Clusters), which is a general project designed to study the physics of
merging clusters by means of multi-wavelength observations.
Description:
Tables provides positions and radial velocities of galaxies and stars
located in the field of the galaxy cluster Abell 2933, Abell 2440 and
Abell 2384, resulting from multi-object spectroscopy performed at ESO
3.6m telescope with the EFOSC2 spectrograph. The error on the
velocities listed in the table is that obtained from the
cross-correlation analysis.
The catalogs list 71 objects for A2933, 97 objects for A2440, and 84
objects for A2384.
