Is the Carter-Israel conjecture correct?
Cosimo Bambi, Katherine Freese, Rohta Takahashi
According to the Carter-Israel conjecture, the end-state of the gravitational collapse of matter is a Kerr-Newman black hole. Nevertheless, neither the theory nor observations can…
Axion braneworld cosmology
Cosimo Bambi, Masahiro Kawasaki, Federico R. Urban
We study axion cosmology in a 5D Universe, in the case of flat and warped extra dimension. The comparison between theoretical predictions and observations constrains the 5D axion d…
Reply to "A note on the innocuous implications of a minimum length in quantum gravity" by P.H. Frampton
Cosimo Bambi, Katherine Freese
We reply to the comment "A note on the innocuous implications of a minimum length in quantum gravity" by P.H. Frampton [Class. Quantum Grav. 26 (2009) 018001, arXiv:arXiv:0808.0283…
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…
Gravitational production of KK states
Cosimo Bambi, Federico R. Urban
Gravitational particle production in the context of braneworlds is considered from a phenomenological point of view. The production of KK modes for bulk fields is discussed and the…
Primordial black holes and the observed Galactic 511 keV line
Cosimo Bambi, Alexander D. Dolgov, Alexey A. Petrov
The observed 511 keV line from the Galactic Bulge is a real challenge for theoretical astrophysics: despite a lot of suggested mechanisms, there is still no convincing explanation…
