Ultra High Energy Neutrinos from Gamma-Ray Burst Afterglows Using the Swift-UVOT Data
Guy Nir, Dafne Guetta, Hagar Landsman +1
We consider a sample of 107 Gamma Ray Bursts (GRBs) for which early UV emission was measured by Swift, and extrapolate the photon intensity to lower energies. Protons accelerated i…
Implication of the non-detection of neutrinos above 2PeV
Lee Yacobi, Dafne Guetta, Ehud Behar
The IceCube telescope has detected diffuse neutrino emission, 20 events of which were reported to be above 60~TeV. In this paper, we fit the diffuse neutrino spectrum using Poisson…
Magnetically-Driven Accretion-Disk Winds and Ultra-Fast Outflows in PG1211+143
Keigo Fukumura, Francesco Tombesi, Demosthenes Kazanas +3
We present a study of X-ray ionization of magnetohydrodynamic (MHD) accretion-disk winds in an effort to constrain the physics underlying the highly-ionized ultra-fast outflows (UF…
