Constraining the properties of the magnetic turbulence in the Geminga region using HAWC -ray data
Rubén López-Coto, Gwenael Giacinti
Observations of extended gamma-ray emission around Galactic cosmic-ray (CR) sources can be used as novel probes of interstellar magnetic fields. Using very-high-energy gamma-ray da…
Inductive spikes and gamma-ray flares from the Crab Nebula
John G. Kirk, Gwenael Giacinti
The ~400 MeV flaring emission from the Crab Nebula is naturally explained as the result of an abrupt reduction in the mass-loading of the pulsar wind. Very few particles are then a…
Galactic Cosmic-Rays in a Breeze
Gwenael Giacinti, Andrew M. Taylor
We study a scenario in which the Fermi bubbles are formed through a Galactocentric outflow of gas and pre-accelerated cosmic-rays (CR). We take into account CR energy losses due to…
Inductive spikes in the Crab Nebula - a theory of gamma-ray flares
John G. Kirk, Gwenael Giacinti
We show that the mysterious, rapidly variable emission at ~400 MeV observed from the Crab Nebula by the AGILE and Fermi experiments could be the result of a sudden drop in the mass…
Reconciling cosmic ray diffusion with Galactic magnetic field models
G. Giacinti, M. Kachelriess, D. V. Semikoz
We calculate the diffusion coefficients of charged cosmic rays (CR) propagating in regular and turbulent magnetic fields. If the magnetic field is dominated by an isotropic turbule…
Cosmic-Ray Anisotropy and the Local Interstellar Turbulence
Gwenael Giacinti, John G. Kirk
We study the role of local interstellar turbulence in shaping the large-scale anisotropy in the arrival directions of TeV-PeV cosmic-rays (CRs) on the sky. Assuming pitch-angle dif…
