Ultra-High Energy Cosmic Rays from Young Neutron Star Winds
P. Blasi, R. I. Epstein, A. V. Olinto
The long-held notion that the highest-energy cosmic rays are of distant extragalactic origin is challenged by observations that events above eV do not exhibit the ex…
Rapid dissipation of magnetic fields due to Hall current
S. I. Vainshtein, S. M. Chitre, A. V. Olinto
We propose a mechanism for the fast dissipation of magnetic fields which is effective in a stratified medium where ion motions can be neglected. In such a medium, the field is froz…
Ultra High Energy Cosmic Ray Accelerators
Angela V. Olinto
The surprising lack of a high energy cutoff in the cosmic ray spectrum at the highest energies together with an apparently isotropic distribution of arrival directions have strongl…
A Limit on Primordial Small-Scale Magnetic Fields from CMB Distortions
K. Jedamzik, V. Katalinic, A. V. Olinto
Spatially varying primordial magnetic fields may be efficiently dissipated prior to the epoch of recombination due to the large viscosity of the baryon-photon fluid. We show that t…
Galactic Ultra-High-Energy Cosmic Rays
A. V. Olinto, R. I. Epstein, P. Blasi
The absence of the expected GZK cutoff strongly challenges the notion that the highest-energy cosmic rays are of distant extragalactic origin. We discuss the possibility that these…
Cosmological Magnetic Fields Limits in an Inhomogeneous Universe
Pasquale Blasi, Scott Burles, Angela V. Olinto
We study the effect of inhomogeneities in the matter distribution of the universe on the Faraday rotation of light from distant QSOs and derive new limits on the cosmological magne…
