The Deutsche Forschungsgemeinschaft (DFG) has awarded Martin Mayer a research fellowship within their Walter-Benjamin Programme. Dr. Martin Mayer, who has been in the Multiwavelength group at the Remeis Observatory since October 2023, is a postdoctoral researcher, working on hot interstellar medium, supernova remnants and neutron stars. He was previously a PhD student at Max-Planck-Institute for extraterrestrial Physics in Garching.

The Walter-Benjamin fellowship is a two-year program aimed at early-career postdoctoral researchers, to carry out an ambitious independent research project at a location of their choice. In cooperation with Prof. Manami Sasaki (Remeis) and Dr. Alison Mitchell (ECAP), Martin Mayer plans to carry out a systematic study of the multiwavelength properties of the environments of rotation-powered pulsars, rapidly rotating neutron stars which accelerate particles to extreme energies. By studying their X-ray synchrotron radiation with SRG/eROSITA, and the corresponding gamma-ray emission at very high energies, they will constrain the physical properties of pulsar wind nebulae and pulsar halos. Key questions include the typical magnetic fields occurring in such objects, the diffusion of particles in their surroundings, and their role as injector of Galactic cosmic rays.
