A triple nucleus in the Brightest Cluster Galaxy in Abell 193

Astrophysics 2009-11-07 v3

Abstract

We present a ground-based near-infrared K-band image and an HST/WFPC2 image of the brightest cluster galaxy in Abell 193 (IC 1695). This object was selected as the central cluster galaxy using X-ray information. Both images reveal a triple nucleus structure. Previously, this galaxy was thought to have only 2 nuclei. We present colours and magnitudes and a colour plot of the three nuclei. The nuclear structure and colours of the nuclei in this galaxy suggest that a merger may have taken place in its recent history.
