| Description | The Little Southern Clump (LSC) was discovered by eROSITA using its PV data of the A3391/95 system. This clump resides in the newly detected filament, the Southern Filament. The LSC shows a soft emission extent toward the northwest, in the direction of the A3395 cluster. We notice a trail of galaxies in the northeast direction, seemingly being accreted onto the clump itself, and co-spatial with an apparent X-ray surface brightness excess. We propose an 85 ks observation to investigate the relationship between an accreted structure with its host filament in the cluster outskirt. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
