Massive early-type stars have very powerful winds that interact with the interstellar medium, depositing great amount of kinetic energy. Besides, their strong stellar photon field ionizes and heats the environment surrounding them. Both phenomena occur at extended scales, parsecs away from the star. The powerful stellar winds, which have supersonic velocities, generate strong shocks in th…
Cosmic rays permeate the whole Galaxy and as they transport through it they interact with the different sources and phases of the interstellar medium. The interaction of the high-energy particles with molecular clouds is of special interest, given that the highly turbulent galactic magnetic field prevents a direct identification of cosmic-ray sources. The detection of photons produced by …
Galactic cosmic rays are believed to be accelerated in shocks via diffusive shock acceleration. This first order Fermi mechanism occurs in shock waves produced in astrophysical sources and in the interstellar medium. Shock waves develop when supersonic perturbations propagate in a medium and are ubiquitous in the Galaxy. Additionally, under the appropriate conditions particles can be eff…
