Runaway stars as cosmic ray injectors inside molecular clouds
Maria Victoria del Valle, Gustavo E. Romero, Reinaldo Santos-Lima
Giant molecular clouds (GMCs) are a new population of gamma-ray sources, being the target of cosmic rays (CRs) -- locally accelerated or not --. These clouds host very young stella…
Cosmic reionization by primordial cosmic rays
Matias Tueros, Maria Victoria del Valle, Gustavo Esteban Romero
After the so-called cosmic recombination, the expanding universe entered into a period of darkness since most of the matter was in a neutral state. About a billion years later, how…
A magnetic reconnection model for explaining the multi-wavelength emission of the microquasars Cyg X-1 and Cyg X-3
Behrouz Khiali, Elisabete M. de Gouveia Dal Pino, Maria V. del Valle
Recent studies have indicated that cosmic ray acceleration by a first-order Fermi process in magnetic reconnection current sheets can be efficient enough in the surrounds of compac…
Runaway massive stars as variable gamma-ray sources
Maria V. del Valle, Gustavo E. Romero
Runaway stars are ejected from their formation sites well within molecular cores in giant dark clouds. Eventually, these stars can travel through the molecular clouds, which are hi…
