Systematics in Aggregated Neutrino Fluxes and Flavor Ratios from Gamma-Ray Bursts
Systematics Aggregated Neutrino Fluxes Flavor Ratios Gamma-Ray Bursts
2011/10/20
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant

We report an analysis of the interstellar-ray emission in the third Galactic quadrant measured
by the Fermi Large Area Telescope. The window encompassing the Galactic plane from longitude 210◦ ...

The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its
first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-ofview
pair-conversion ...

We report on the search for 0.1{10 GeV emission from magnetars in 17 months of Fermi Large
Area Telescope (LAT) observations. No signi cant evidence for gamma-ray emission from any of the currently-k...
Evolution of massive Be and Oe stars at low metallicity towards the Long Gamma Ray bursts\footnote{Based on ESO runs 069.D-0275(A), 072.D-0245(A) and (C).}

Several studies have shown recently that at low metallicity B-type stars rotate faster than in environments of high metallicity. This is a typical case in the SMC. As a consequence, it is expected tha...
