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…
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…
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…
Spin polarization of electrons by ultraintense lasers
D. Del Sorbo, D. Seipt, T. G. Blackburn +4
In a strong magnetic field, ultra-relativistic electrons or positrons undergo spin flip transitions as they radiate, preferentially spin polarizing in one direction -- the Sokolov-…
