The prospects of finding the first quasars in the universe
Dominik R. G. Schleicher, Marco Spaans, Ralf S. Klessen
We study the prospects of finding the first quasars in the universe with ALMA and JWST. For this purpose, we derive a model for the high-redshift black hole population based on obs…
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…
The formation of the first galaxies and the transition to low-mass star formation
Thomas H. Greif, Dominik R. G. Schleicher, Jarrett L. Johnson +6
The formation of the first galaxies at redshifts z ~ 10-15 signaled the transition from the simple initial state of the universe to one of ever increasing complexity. We here revie…
Influence of primordial magnetic fields on 21 cm emission
Dominik R. G. Schleicher, Robi Banerjee, Ralf S. Klessen
Magnetic fields in the early universe can significantly alter the thermal evolution and the ionization history during the dark ages. This is reflected in the 21 cm line of atomic h…
Effects of primordial chemistry on the cosmic microwave background
D. R. G. Schleicher, D. Galli, F. Palla +4
Previous works have demonstrated that the generation of secondary CMB anisotropies due to the molecular optical depth is likely too small to be observed. In this paper, we examine…
