Gamma-ray emission from massive stars interacting with AGN jets
Anabella Araudo, Valenti Bosch-Ramon, Gustavo E. Romero
Dense populations of stars surround the nuclear regions of galaxies. In active galactic nuclei, these stars can interact with the relativistic jets launched by the supermasive blac…
Neutrinos from collapsars
Florencia L. Vieyro, Gustavo E. Romero, Orlando L. G. Peres
Long gamma-ray bursts (GRBs) are associated with the gravitational collapse of very massive stars. The central engine of a GRB can collimate relativistic jets that propagate inside…
Gamma-ray emission from early-type stars interacting with AGN jets
Anabella T. Araudo, Valenti Bosch-Ramon, Gustavo E. Romero
We study the interaction of early-type stars with the jets of active galactic nuclei. A bow-shock will form as a consequence of the interaction of the jet with the winds of stars a…
The star forming region Monoceros R2 as a gamma-ray source
Josep Martí, Pedro L. Luque-Escamilla, Álvaro J. Muñoz-Arjonilla +6
Context. After the release of the gamma-ray source catalog produced by the Fermi satellite during its first two years of operation, a significant fraction of sources still remain u…
Gravitational Lensing of Neutrino from Collapsars
Florencia L. Vieyro, Gustavo E. Romero
We study neutrino emission from long gamma-ray bursts. The collapse of very massive stars to black holes, and the consequent jet formation, are expected to produce high-energy neut…
Episodic gamma-ray and neutrino emission from the low mass X-ray binary GRO J0422+32
Florencia L. Vieyro, Yolanda Sestayo, Gustavo E. Romero +1
GRO J0422+32 is a member of the class of low-mass X-ray binary (LMXB) sources, discovered during an outburst in 1992. Along the entire episode ( days) a persistent power-…
