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,…
Dynamical black hole in a bouncing universe
Daniela Pérez, Santiago E. Perez Bergliaffa, Gustavo E. Romero
We analyze the causal structure of McVittie spacetime for a classical bouncing cosmological model. In particular, we compute the trapping horizons of the metric and integrate the t…
Nonthermal processes in hot accretion flows onto supermassive black holes: An inhomogeneous model
Eduardo M. Gutiérrez, Florencia L. Vieyro, Gustavo E. Romero
Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a…
