Particle acceleration and non-thermal emission in colliding-wind binary systems
J. M. Pittard, G. E. Romero, G. S. Vila
We present a model for the creation of non-thermal particles via diffusive shock acceleration in a colliding-wind binary. Our model accounts for the oblique nature of the global sh…
Colliding-wind binary systems: Diffusive shock acceleration and non-thermal emission
J. M. Pittard, G. S. Vila, G. E. Romero
We present a model for the non-thermal emission from a colliding-wind binary. Relativistic protons and electrons are assumed to be accelerated through diffusive shock acceleration…
High-energy signatures of binary systems of supermassive black holes
Gustavo E. Romero, Gabriela S. Vila, Daniela Pérez
Context. Binary systems of supermassive black holes are expected to be strong sources of long gravitational waves prior to merging. These systems are good candidates to be observed…
Spectral energy distribution, polarization, and synthetic radio maps of Cygnus X-1: a lepto-hadronic jet model
C. Pepe, G. S. Vila, G. E. Romero
In this work we combine SEDs, radio maps and polarization observations to understand the emission mechanisms in Cygnus X-1. Our radiative model indicates that the MeV emission orig…
Lepto-hadronic model for the broadband emission of Cygnus X-1
Carolina Pepe, Gabriela S. Vila, Gustavo E. Romero
Cygnus X-1 is a well observed microquasar. Broadband observations at all wavelengths have been collected over the years. The origin of the MeV tail observed with COMPTEL and INTEGR…
Parametrization of gamma-ray production cross-sections for pp interactions in a broad proton energy range from the kinematic threshold to PeV energies
Ervin Kafexhiu, Felix Aharonian, Andrew M. Taylor +1
Using publicly available Monte Carlo codes as well as compilation of published data on p--p interactions for proton kinetic energy below 2 GeV, we parametrize the energy spectra an…
