Towards understanding the physics of collisionless relativistic shocks
Guy Pelletier, Andrei Bykov, Don Ellison +1
Relativistic astrophysical collisionless shocks represent outstanding dissipation agents of the huge power of relativistic outflows produced by accreting black holes, core collapse…
Particle acceleration in relativistic outflows
Andrei Bykov, Neil Gehrels, Henric Krawczynski +3
In this review we confront the current theoretical understanding of particle acceleration at relativistic outflows with recent observational results on various source classes thoug…
Circum-stellar medium around rotating massive stars at solar metallicity
Cyril Georgy, Rolf Walder, Doris Folini +3
Aims. Observations show nebulae around some massive stars but not around others. If observed, their chemical composition is far from homogeneous. Our goal is to put these observati…
Cosmic rays: constraints from future MeV detectors
Giada Peron, Sarah Recchia, Stefano Menchiari +4
Cosmic rays are charged energetic particles that permeate the interstellar medium. Their sizeable energy share and penetration power makes them essential players in the dynamical a…
Direct detection of the non-thermal X-ray emission from the Arches star cluster
Roman Krivonos, Alexey Vikhlinin, Andrei Bykov +2
The compact stellar clusters have emerged as particularly promising candidates for cosmic rays (CR) accelerators. The star clusters, recently observed in gamma-rays, are also known…
Cosmic Rays and Interstellar Medium with Gamma-Ray Observations at MeV Energies
Elena Orlando, Isabelle Grenier, Vincent Tatischeff +10
Latest precise cosmic-ray (CR) measurements and present gamma-ray observations have started challenging our understanding of CR transport and interaction in the Galaxy. Moreover, b…
