Survival of black holes through a cosmological bounce
Daniela Pérez, Gustavo E. Romero
We analyze whether a black hole can exist and survive in a universe that goes through a cosmological bounce. To this end, we investigate a central inhomogeneity embedded in a bounc…
Non-thermal emission in hyper-velocity and semi-relativistic stars
J. R. Martinez, S. del Palacio, V. Bosch-Ramon +1
Context. There is a population of runaway stars that move at extremely high speeds with respect to their surroundings. The fast motion and the stellar wind of these stars, plus the…
The non-thermal emission from the colliding-wind binary Apep
S. del Palacio, P. Benaglia, M. De Becker +2
The recently discovered massive binary system Apep is the most powerful synchrotron emitter among the known Galactic colliding-wind binaries. This makes this particular system of g…
The content of astrophysical jets
Gustavo E. Romero
Jets, collimated outflows of particles and fields, are observed in a wide variety of astrophysical systems, including Active Galactic Nuclei of various types, microquasars, gamma-r…
Cosmic-ray production from neutron escape in microquasar jets
G. J. Escobar, L. J. Pellizza, G. E. Romero
The origin of Galactic cosmic rays remains a matter of debate, but supernova remnants are commonly considered to be the main place where high-energy cosmic rays are accelerated. Ne…
Black hole in asymmetric cosmological bounce
Daniela Pérez, Santiago E. Perez Bergliaffa, Gustavo E. Romero
We determine the causal structure of the McVittie spacetime for a cosmological model with an asymmetric bounce. The analysis includes the computation of trapping horizons, regular,…
