Supernova remnants have long been considered as a promising candidate for sources of Galactic cosmic rays. However, modelling cosmic-ray transport around these sources is complicated by the fact that the overdensity of cosmic rays close to their acceleration site can lead to self-confinement, that is the generation of turbulence upon which these particles scatter. Such a highly non-linear problem can be addressed by numerically solving the coupled differential equations describing the evolution…

Diffuse gamma-ray emission from self-confined cosmic rays around Galactic sources

The propagation of particles accelerated at supernova remnant shocks and escaping the parent remnants is likely to proceed in a strongly non-linear regime, due to the efficient self-generation of

Morphology of supernova remnants and their halos

Context. Supernova remnants (SNRs) are known to accelerate particles to relativistic energies, on account of their nonthermal emis- sion. The observational progress from radio to gamma-ray

Non-linear diffusion of cosmic rays escaping from supernova remnants – I. The effect of neutrals

Supernova remnants are believed to be the main sources of galactic cosmic rays (CR). Within this framework, particles are accelerated at supernova remnant shocks and then released in the interstellar

The cosmic ray-driven streaming instability in astrophysical and space plasmas

Energetic non-thermal particles, or cosmic rays, are a major component of astrophysical plasmas next to magnetic fields, radiation, and thermal gas. Cosmic rays are usually sub-dominant in density

Non-linear diffusion of cosmic rays escaping from supernova remnants – II. Hot ionized media

We study the problem of the escape and transport of cosmic rays (CRs) from a source embedded in a fully ionized, hot phase of the interstellar medium (HIM). In particular, we model the CR escape and

Constraining the cosmic ray spectrum in the vicinity of the supernova remnant W28: from sub-GeV to multi-TeV energies

Context. Supernova remnants interacting with molecular clouds are ideal laboratories to study the acceleration of particles at shock waves and their transport and interactions in the surrounding

Dynamical Effects of Cosmic Rays on the Medium Surrounding Their Sources

Cosmic rays (CRs) leave their sources mainly along the local magnetic field; in doing so they excite both resonant and nonresonant modes through streaming instabilities. The excitation of these modes

Nonlinear diffusion of cosmic rays escaping from supernova remnants: Cold partially neutral atomic and molecular phases

Aims. We aim to elucidate cosmic ray (CR) propagation in the weakly ionized environments of supernova remnants (SNRs) basing our analysis on the cosmic ray cloud (CRC) model. Methods. We solved two

Self-generated cosmic-ray confinement in TeV halos: Implications for TeV γ -ray emission and the positron excess

Recent observations have detected extended TeV gamma-ray emission surrounding young and middle-aged pulsars. The morphology of these "TeV halos" requires cosmic-ray diffusion to be locally suppressed
