Cosmic-rays (CRs) have been recognized to play an important role in the galactic ecosystem through CR feedback. The key underlying microphysics lie in the CR gyro-resonant instabilities, which trigger the growth of Alfv’en waves that lead to energy and momentum exchange between the CRs and the background plasmas, as well as CR self-confinement. I will present simulations of the CR...
In the last decade several Young Star Clusters have been associated to diffuse gamma-ray sources both in the GeV and TeV energy ranges. The origin of such emission is still debated, however hadronic processes due to interaction between gas and locally accelerated cosmic rays seems to be favored at least in some cases. The acceleration mechanism is probably related to powerful stellar winds...
Unveiling the origin of the cosmic-ray (CR) flux observed at Earth remains among the main challenges in the field of astroparcle physics. The Galactic CR component is believed to be produced bysupernova remnants (SNRs) as a result of diffusive shock acceleration, though the acvity of this class of sources in the knee region is yet to be proven. In this context, the process through which...
Currently, the bulk of Galactic VHE sources are associated with isolated, rotation powered neutron stars (i.e. pulsars). However, how pulsars produce such sources is poorly understood. Answering this question requires understanding the evolution of the pulsar wind nebulae (PWN) produced by the neutron star -- where particles are believed to be accelerated to the required PeV energies and...
The microquasar system SS 433 provides a unique opportunity to study mildly relativistic collimated jets in our own Galaxy. From its core, a binary system hosting a stellar-mass black hole, two persistent, semi-relativistic jets are launched, almost perpendicular to the line of sight. X-ray observations reveal that these jets extend out to around 100 pc on either side of the central system,...
