Abstract: Heavy-ion induced scintillation is accompanied by interesting effects which are mainly due to secondary electrons. These electrons are produced during the stopping of the primary projectiles. Strong signatures of such effects like recombination and the formation of a halo around the projectile’s trajectory will be presented and discussed. Two experiments in which this plays an important role have recently been performed at the Munich Tandem accelerator. In a study in collaboration with GSI/FAIR…

Abstract: Nongravitational interactions between dark matter particles can impact the structure of dark matter halos to solve the longstanding core/cusp problem for galactic rotation curves. Here I discuss new work aimed at constraining these effects on complementary scales. These include galaxy groups and clusters, on the larger side, and subhalos in within the Milky Way on the smaller side.

Abstract: Modular symmetries might be relevant for phenomena in physics and cosmology. We sketch an application in the framework of natural inflation and then concentrate on the recent proposal of "modular flavor symmetries" that allow new insights for a unified description of masses and mixing angles of quarks and leptons.  https://tum-conf.zoom.us/j/91287766524 Password: mockpwd
