Description
The eROSITA observation of the interacting A3391/95 galaxy cluster system has revealed an impressive overview of its surroundings. In approximately 14 square degrees of sky area with a nominal exposure of several ks over most of the area in the 0.2—2 keV energy band, we have found more than 50 extended objects. These objects are mainly fore- and background galaxy groups and clusters as well as a non-negligible number of clumps, which are presumably falling onto the main galaxy cluster system. In this work, we present some X-ray properties of the most prominent objects as well as a preliminary estimation of the impact of nearby large-scale structures, like A3391/95, will have on the eRASS cluster selection function.
