Cosmic constraints rule out s-wave annihilation of light dark matter
Dominik R. G. Schleicher, Simon C. O. Glover, Robi Banerjee +1
Light dark matter annihilating into electron-positron pairs emits a significant amount of internal bremsstrahlung that may contribute to the cosmic gamma-ray background. The amount…
Dark stars: Implications and constraints from cosmic reionization and extragalactic background radiation
Dominik R. G. Schleicher, Robi Banerjee, Ralf S. Klessen
Dark stars powered by dark matter annihilation have been proposed as the first luminous sources in the universe. These stars are believed to form in the central dark matter cusp of…
Ionization front-driven turbulence in the clumpy interstellar medium
Thomas Peters, Robi Banerjee, Ralf S. Klessen
We present 3D radiation-gasdynamical simulations of an ionization front running into a dense clump. In our setup, a B0 star irradiates an overdensity which is at a distance of 10 p…
Reionization - A probe for the stellar population and the physics of the early universe
Dominik R. G. Schleicher, Robi Banerjee, Ralf S. Klessen
We calculate the reionization history for different models of the stellar population and explore the effects of primordial magnetic fields, dark matter decay and dark matter annihi…
