Study of the Little Southern Clump in the A3391/95 Southern Filament

The Little Southern Clump (LSC) was discovered by eROSITA using its PV data ofthe A3391/95 system. This clump resides in the newly detected filament, theSouthern Filament. The LSC shows a soft emission extent toward the northwest, inthe direction of the A3395 cluster. We notice a trail of galaxies in thenortheast direction, seemingly being accreted onto the clump itself, andcospatial with an apparent Xray surface brightness excess. We propose an 85 ksobservation to investigate the relationship between an accreted structure withits host filament in the cluster outskirt. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
