Tidal disruption jets of supermassive black holes as hidden sources of cosmic rays: explaining the IceCube TeV-PeV neutrinos
Xiang-Yu Wang, Ruo-Yu Liu
Cosmic ray interactions that produce high-energy neutrinos also inevitably generate high-energy gamma rays, which finally contribute to the diffuse high-energy gamma-ray background…

The complex X-ray system IGR J11014-6103 (a.k.a. the Lighthouse nebula) is composed of a bow-shock pulsar wind nebula (PWN) as well as large-scale jet-like features, all launched b…
Turbulent Reconnection in Relativistic Plasmas And Effects of Compressibility

We perform simulations of Cherenkov Telescope Array (CTA) observations of a young supernova remnant RX J1713.7-3946. This target is not only one of the brightest sources ever disco…
2FHL: The Second Catalog of Hard Fermi-LAT Sources
LAT Collaboration
We present a catalog of sources detected above 50 GeV by the {\it Fermi}-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the…
Search for gamma-ray emission from the Coma Cluster with six years of Fermi-LAT data
LAT Collaboration, Y. Rephaeli
We present results from γ-ray observations of the Coma cluster incorporating 6 years of Fermi-LAT data and the newly released {\emph{Pass 8}} event-level analysis. Our analysis of…
Unified model for cosmic rays above eV and the diffuse gamma-ray and neutrino backgrounds
G. Giacinti, M. Kachelriess, O. Kalashev +2
We investigate how the extragalactic proton component derived within the "escape model" can be explained by astrophysical sources. We consider as possible cosmic ray (CR) sources n…
Re-examination of the Expected gamma-ray emission of supernova remnant SN 1987A
E. G. Berezhko, L. T. Ksenofontov, H. J. Voelk
A nonlinear kinetic theory, combining cosmic-ray (CR) acceleration in supernova remnants (SNRs) with their gas dynamics, is used to re-examine the nonthermal properties of the remn…
Rapid cosmic-ray acceleration at perpendicular shocks in supernova remnants
Makoto Takamoto, John G. Kirk
Perpendicular shocks are shown to be rapid particle accelerators that perform optimally when the ratio of the shock speed to the particle speed roughly equals the ratio…
On transition of propagation of relativistic particles from the ballistic to the diffusion regime
A. Y. Prosekin, S. R. Kelner, F. A. Aharonian
A stationary distribution function that describes the entire processes of propagation of relativistic particles, including the transition between the ballistic and diffusion regime…
Energy and Flux Measurements of Ultra-High Energy Cosmic Rays Observed During the First ANITA Flight
H. Schoorlemmer, K. Belov, A. Romero-Wolf +55
The first flight of the Antarctic Impulsive Transient Antenna (ANITA) experiment recorded 16 radio signals that were emitted by cosmic-ray induced air showers. For 14 of these even…
Prospect for Future MeV Gamma-ray Active Galactic Nuclei Population Studies
Yoshiyuki Inoue, Yasuyuki T. Tanaka, Hirokazu Odaka +5
While the X-ray, GeV gamma-ray, and TeV gamma-ray skies have been extensively studied, the MeV gamma-ray sky is not well investigated after the Imaging Compton Telescope (COMPTEL)…
Dark matter annihilation and decay in dwarf spheroidal galaxies: The classical and ultrafaint dSphs
V. Bonnivard, C. Combet, M. Daniel +8
Dwarf spheroidal (dSph) galaxies are prime targets for present and future gamma-ray telescopes hunting for indirect signals of particle dark matter. The interpretation of the data…
