Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…
TeV gamma-ray survey of the Northern sky using the ARGO-YBJ detector
YBJ Collaboration, B. Bartoli, P. Bernardini +94
The ARGO-YBJ detector is an extensive air shower array that has been used to monitor the northern -ray sky at energies above 0.3 TeV from 2007 November to 2013 January. In this…
Hadronic Gamma-Ray and Neutrino Emission from Cygnus X-3
N. Sahakyan, G. Piano, M. Tavani
Cygnus X-3 (Cyg X-3) is a remarkable Galactic microquasar (X-ray binary) emitting from radio to -ray energies. In this paper, we consider hadronic model of emission of -rays…
An updated list of AGILE bright gamma-ray sources and their variability in pointing mode

We present a variability study of a sample of bright gamma-ray (30 MeV -- 50 GeV) sources. This sample is an extension of the first AGILE catalogue of gamma-ray sources (1AGL), obt…
Dark Matter Constraints from Observations of 25 Milky Way Satellite Galaxies with the Fermi Large Area Telescope
LAT Collaboration, M. Ackermann, A. Albert +119
The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of ast…
Determination of the Point-Spread Function for the Fermi Large Area Telescope from On-orbit Data and Limits on Pair Halos of Active Galactic Nuclei
LAT Collaboration
The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope is a pair-conversion telescope designed to detect photons with energies from 20 MeV to > 300 GeV. The pre-laun…
PSR J2021+4026 in the Gamma Cygni region: the first variable gamma-ray pulsar seen by the Fermi LAT
LAT collaboration
Long-term monitoring of PSR J2021+4026 in the heart of the Cygnus region with the Fermi Large Area Telescope (LAT) unveiled a sudden decrease in flux above 100 MeV over a time scal…
Modelling the Kinked Jet of the Crab Nebula
A. Mignone, E. Striani, M. Tavani +1
We investigate the dynamical propagation of the South-East jet from the Crab pulsar interacting with supernova ejecta by means of three-dimensional relativistic MHD numerical simul…
Search for long-lived gravitational-wave transients coincident with long gamma-ray bursts
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +875
Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We inv…
Gravitational waves from known pulsars: results from the initial detector era

We present the results of searches for gravitational waves from a large selection of pulsars using data from the most recent science runs (S6, VSR2 and VSR4) of the initial generat…
The cosmic-ray positron energy spectrum measured by PAMELA
PAMELA Collaboration, O. Adriani, G. C. Barbarino +63
Precision measurements of the positron component in the cosmic radiation provide important information about the propagation of cosmic rays and the nature of particle sources in ou…
Constraints on WIMP Annihilation for Contracted Dark Matter in the Inner Galaxy with the Fermi-LAT
German A. Gomez-Vargas, Miguel A. Sanchez-Conde, Ji-Haeng Huh +7
We derive constraints on parameters of generic dark matter candidates by comparing theoretical predictions with the gamma-ray emission observed by the Fermi-LAT from the region aro…
Search for cosmic-ray induced gamma-ray emission in Galaxy Clusters
M. Ackermann, M. Ajello, A. Albert +123
Current theories predict relativistic hadronic particle populations in clusters of galaxies in addition to the already observed relativistic leptons. In these scenarios hadronic in…
Associating long-term gamma-ray variability with the superorbital period of LS I 61 303
LAT Collaboration
Gamma-ray binaries are stellar systems for which the spectral energy distribution (discounting the thermal stellar emission) peaks at high energies. Detected from radio to TeV gamm…
