The role of supernovae inside AGN jets in UHECR acceleration
Valenti Bosch-Ramon
Jets of active galactic nuclei are potential accelerators of ultra high-energy cosmic rays. Supernovae can occur inside these jets and contribute to cosmic ray acceleration, partic…
Relativistic hydrodynamical simulations of the effects of the stellar wind and the orbit on high-mass microquasar jets
Maxim V. Barkov, Valenti Bosch-Ramon
High-mass microquasar jets, produced in an accreting compact object in orbit around a massive star, must cross a region filled with stellar wind. The combined effects of the wind a…
On the formation of TeV radiation in LS 5039
Dmitry Khangulyan, Felix Aharonian, Valenti Bosch-Ramon
The recent detections of TeV gamma-rays from compact binary systems show that relativistic outflows (jets or winds) are sites of effective acceleration of particles up to multi-TeV…
Unveiling properties of the non-thermal X-ray production in the gamma-ray binary LS 5039 using the long-term pattern of its fast X-ray variability
Hiroki Yoneda, Valenti Bosch-Ramon, Teruaki Enoto +5
Gamma-ray binary systems, a subclass of high-mass X-ray binaries, show non-thermal emissions from radio to TeV. While efficient electron acceleration is considered to take place in…
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…
Investigating the Role of Pre-supernova Massive Stars in the Acceleration of Galactic Cosmic Rays
Michael De Becker, Santiago del Palacio, Paula Benaglia +5
Galactic cosmic rays (GCRs) constitute a significant part of the energy budget of our Galaxy, and the study of their accelerators is of high importance in modern astrophysics. Thei…
