Dark Stars: the First Stars in the Universe may be powered by Dark Matter Heating
Katherine Freese, Peter Bodenheimer, Paolo Gondolo +1
A new line of research on Dark Stars is reviewed, which suggests that the first stars to exist in the universe were powered by dark matter heating rather than by fusion. Weakly Int…
Review of Observational Evidence for Dark Matter in the Universe and in upcoming searches for Dark Stars
Katherine Freese
Over the past decade, a consensus picture has emerged in which roughly a quarter of the universe consists of dark matter. The observational evidence for the existence of dark matte…
Apparent shape of super-spinning black holes
Cosimo Bambi, Katherine Freese
We consider the possibility that astrophysical Black Holes (BHs) can violate the Kerr bound; i.e., they can have angular momentum greater than BH mass, . We discuss implicat…
Implications of primordial black holes on the first stars and the origin of the super--massive black holes
Cosimo Bambi, Douglas Spolyar, Alexander D. Dolgov +2
If the cosmological dark matter has a component made of small primordial black holes, they may have a significant impact on the physics of the first stars and on the subsequent for…
Dark Stars: Dark Matter in the First Stars leads to a New Phase of Stellar Evolution
Katherine Freese, Douglas Spolyar, Anthony Aguirre +4
The first phase of stellar evolution in the history of the universe may be Dark Stars, powered by dark matter heating rather than by fusion. Weakly interacting massive particles, w…
Compatibility of DAMA/LIBRA dark matter detection with other searches
Christopher Savage, Graciela Gelmini, Paolo Gondolo +1
The DAMA/NaI and DAMA/LIBRA annual modulation data, which may be interpreted as a signal for the existence of weakly interacting dark matter (WIMPs) in our galactic halo, are exami…
