To contain the spread of corona virus infections, the MPA has enacted certain changes to protect its employees. For the time being, the MPA will not offer public events, and its staff will not undertake travel or attend conferences. Meetings will primarily be held via video conferencing.
It might be difficult to reach some staff members by telephone, please use Email instead. Mail continues to be received. Please note, however, that there might be some delays in getting a response.

The Max Planck Society has appointed Simona Vegetti at MPA to head a Lise Meitner Excellence Group. Simona Vegetti will use strong gravitational lensing observations to measure the abundance and structural properties of dark matter haloes and thereby provide clean observational constraints on the nature of dark matter. As part of the programme, the group is endowed with an internationally competitive budget for material and human resources.

Galaxy clusters are dynamic systems that grow by continuously accreting large and small chunks of matter. This accretion process should give rise to a rich substructure in the dark matter distribution within the clusters and to shocks and “cold fronts” in the hot baryonic gas. Recent SRG/eROSITA observations provided an unprecedented X-ray view of the Coma cluster, revealing intricate signatures of the merger process, which are predicted by numerical simulations.
