The meeting was the annual gathering of all members and associated researchers of our research unit as well as of selected experts external to the research unit. Participants had the opportunity to present their research topics, their numerical, computational or analytical techniques, their barriers and obstacles to progress, current difficulties and immediate problems as well as their near-future goals. There was also ample space to discuss conceptual models, recent findings up to now, as well as to plan future starting points of research. We gained insight about different approaches, about solution finding and we planned future collaborations and potential synergies and enriched our colleagues’ work with fruitful hints.

To empower scientists belonging to under-represented groups of the society and to advance towards equality in academia, a workshop on equality, diversity and inclusion took place during sessions spread over the annual assembly. The workshop was conceived and delivered by Prof. Tomas Brage from Lunds Universitet. This in-depth workshop took place both in plenum rounds, in interactive sessions as well as in smaller, relaxed rounds.

The galaxy cluster PSZRX G181.53+21.43 emits diffuse radio emission, as detected in data from the LOFAR Two-metre Sky Survey DR2. The left- and right-hand side panels show sky maps of the galaxy cluster at 144 MHz with the yellow line depicting the 3 sigma X-ray contour line, while the centre panel displays the Sloan Digital Sky Survey map with the LOFAR contours. At the outskirts of the cluster, three diffuse radio sources (labelled A, B and C) are detected. Source A is identified with a radio relic, revealing the presence of ultra-relativistic electrons gyrating in a large-scale magnetic field. Sources B and C are attributed with a wide-angle tailed radio galaxy and a Fanaroff-Riley class I radio galaxy, respectively, and are associated with galaxy mergers during the evolution of the host cluster. The interrelations of galaxy clusters and AGN in them are studied in projects 6 and 7 and will also be discussed in the annual assembly.
