Abstract
We present results from a Chandra observation of EXO 0423.4-0840, which was originally catalogued as an X-ray source associated with a BL Lac object. There is no X-ray point source at the nominal position of the BL Lac, but the Chandra data find extended cluster emission with an "arc-like" structure in the centre which may be connected with an AGN or merger activity.
