Abell 1795 is a galaxy cluster in the Abell catalogue.
Black holes
In January 2014, scientists using data collected by the Chandra X-Ray Observatory and other telescopes reported they had found evidence of a new supermassive black hole candidate disrupting a star in a dwarf galaxy in the Abell 1795 cluster.[4][5]
