Gamma-ray emission from Wolf-Rayet stars interacting with AGN jets
Anabella T. Araudo, Valenti Bosch-Ramon, Gustavo E. Romero
Dense populations of stars surround the nuclear regions of galaxies. In this work, we study the interaction of a WR star with relativistic jets in active galactic nuclei. A bow-sha…
A two-component model for the high-energy variability of blazars. Application to PKS 2155-304
Matías M. Reynoso, Gustavo E. Romero, María C. Medina
We study the production of VHE emission in blazars as a superposition of a steady component from a baryonic jet and a time- dependent contribution from an inner e-e+ beam launched…
On the origin of the jet-like radio/X-ray morphology of G290.1-0.8
Federico García, Jorge A. Combi, Juan F. Albacete-Colombo +3
The origin and evolution of supernova remnants of the mixed-morphology class is not well understood. Several remnants present distorted radio or X-ray shells with jet-like structur…
Nonthermal processes and neutrino emission from the black hole GRO J0422+32 in a bursting state
F. L. Vieyro, Y. Sestayo, G. E. Romero +1
GRO J0422+32 is a member of the class of low-mass X-ray binaries (LMXBs). It was discovered during an outburst in 1992. During the entire episode a persistent power-law spectral co…
AE Aurigae: first detection of non-thermal X-ray emission from a bow shock produced by a runaway star
J. Lopez-Santiago, M. Miceli, M. V. del Valle +6
Runaway stars produce shocks when passing through interstellar medium at supersonic velocities. Bow shocks have been detected in the mid-infrared for several high-mass runaway star…
Non-thermal processes in bowshocks of runaway stars. Application to Zeta Oph
María Victoria del Valle, Gustavo E. Romero
Runaway massive stars are O- and B-type stars with high spatial velocities with respect to the interstellar medium. These stars can produce bowshocks in the surrounding gas. Bowsho…
