Local radiative feedback in the formation of the first protogalaxies
Jarrett L. Johnson, Thomas H. Greif, Volker Bromm
The formation of the first galaxies is influenced by the radiative feedback from the first generations of stars. This feedback is manisfested by the heating and ionization of the g…
The aftermath of the first stars: massive black holes
Jarrett L. Johnson, Volker Bromm
We investigate the evolution of the primordial gas surrounding the first massive black holes formed by the collapse of Population III stars at redshifts z > 20. Carrying out three-…
Two populations of metal-free stars in the early Universe
Thomas H. Greif, Volker Bromm
We construct star formation histories at redshifts z > 5 for two physically distinct populations of primordial, metal-free stars, motivated by theoretical and observational argumen…
GRB Cosmology and the First Stars
Volker Bromm, Abraham Loeb
Gamma-Ray Bursts (GRBs) are unique probes of the cosmic star formation history and the state of the intergalactic medium up to the redshifts of the first stars. In particular, the…
