On March 1, 2025, our spokesperson Prof. Julia Tjus became affiliated professor at the Department of Space, Earth and Environment at Chalmers University of Technology in Gothenburg. This honor recognizes her long-standing connection to the Swedish university.
The collaboration is particularly fruitful as Julia’s expertise in high-energy astrophysics perfectly complements the extensive experience of researchers at Chalmers University in measuring and analyzing low-energy radiation.
This synergy allows for deeper insights into extreme cosmic events such as supernova explosions and active galactic nuclei and thus for a better understanding of the origins and properties of cosmic rays.
The aim of the affiliated professorship is to intensify existing collaborations and initiate new projects, especially in connection with the IceCube Neutrino Observatory.

We are excited to announce that Dr. Christopher Riseley has been appointed as a new PI at our CRC.
Chris is a Junior Professor of Radio Astronomy at the Astronomical Institute of Ruhr-University Bochum (AIRUB). His research focuses on using radio telescopes worldwide to study clusters of galaxies. He aims to answer key scientific questions related to diffuse radio sources in galaxy clusters, including canonical relics, haloes, and mini-haloes. Chris is also exploring the unique sources discovered by the precursor instruments for the Square Kilometre Array (SKA).
Specializing in long-wavelength radio astronomy, Chris works extensively with data from the LOw-Frequency ARray (LOFAR), the Murchison Widefield Array (MWA), the Australian Square Kilometre Array Pathfinder (ASKAP), and the MeerKAT telescope in South Africa.
In the coming years Chris will use these instruments to explore galaxy groups, understanding the interplay between galaxies and their environments. Within the CRC, Chris will apply his radio astronomy expertise to studying the rich physics of dwarf galaxies and nearby galaxies in these environments, answering questions related to dark matter, Cosmic Rays, galaxy evolution, and feedback mechanisms.

For two days in February, all SFB1491 researchers came together at TU Dortmund to discuss the latest results, covering a wide range of topics including the search for dark matter, investigating (cosmic) magnetic fields, the modeling of accretion and ejection phenomena in astrophysics, and the exploration of cosmic rays and neutrinos in astrophysical as well as collider experiments.
A special highlight were the keynote talks by Dr. Imre Bartos (University of Florida) on "The Expanding Gravitational Wave Horizon: Emerging Opportunities for
Multimessenger Discovery" and Dr. Daniel Verscharen (Mullard Space Science Laboratory) on "Electron heat flux in structured plasmas: collisions, trapping, and
wave-particle interactions".
