Deep GMRT radio observations and a multi-wavelength study of the region around HESS J1858+020
J. M. Paredes, C. H. Ishwara-Chandra, V. Bosch-Ramon +3
There are a number of very high energy sources in the Galaxy that remain unidentified. Multi-wavelength and variability studies, and catalogue searches, are powerful tools to ident…
Formation of large-scale magnetic structures associated with the Fermi bubbles
Maxim V. Barkov, Valenti Bosch-Ramon
The Fermi bubbles are part of a complex region of the Milky Way. This region presents broadband extended non-thermal radiation, apparently coming from a physical structure rooted i…

VERITAS Collaboration, E. Aliu, S. Archambault +297
HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations with ground-based observatories both in the northern and southern hemispheres…
Constraints on axionlike particles with H.E.S.S. from the irregularity of the PKS 2155-304 energy spectrum
H. E. S. S. Collaboration, A. Abramowski, F. Acero +211
Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising h…
Analysis of X-ray spectral variability and black hole mass determination of the NLS1 galaxy Mrk 766
S. Giacche`, R. Gilli, L. Titarchuk
We present an XMM-Newton time-resolved spectral analysis of the NLS1 galaxy Mrk 766. We analyse eight available observations of the EPIC-pn camera taken between May 2000 and June 2…
H.E.S.S. Observations of the Crab during its March 2013 GeV Gamma-Ray Flare
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
Context. On March 4, 2013, the Fermi-LAT and AGILE reported a flare from the direction of the Crab Nebula in which the high-energy (HE; E > 100 MeV) flux was six times above its qu…
The stability of strong waves and its implications for pulsar wind shocks
Iwona Mochol, John G. Kirk
Strong waves can mediate a shock transition between a pulsar wind and its surroundings, playing the role of an extended precursor, in which the energy is effectively transferred fr…
On The {\it Fermi} -Lat Surplus of the Diffuse Galactic Gamma-Ray Emission
Heinrich J. Voelk, Evgeny G. Berezhko
Recent observations of the diffuse Galactic \gr emission (DGE) by the {\it Fermi} Large Area Telescope ({\it Fermi}-LAT) have shown significant deviations, above a few GeV until ab…
Simple analytical approximations for treatment of inverse Compton scattering of relativistic electrons in the black-body radiation field
Dmitry Khangulyan, Felix A. Aharonian, Stanislav R. Kelner
The inverse Compton (IC) scattering of relativistic electrons is one of the major gamma-ray production mechanisms in different environments. Often the target photons for the IC sca…
HESS J1818-154, a new composite supernova remnant discovered in TeV gamma rays and X-rays
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
Composite supernova remnants (SNRs) constitute a small subclass of the remnants of massive stellar explosions where non-thermal radiation is observed from both the expanding shell-…
Diffuse PeV neutrinos from EeV cosmic ray sources: semi-relativistic hypernova remnants in star-forming galaxies
Ruo-Yu Liu, Xiang-Yu Wang, Susumu Inoue +2
We argue that the excess of sub-PeV/PeV neutrinos recently reported by IceCube could plausibly originate through pion-production processes in the same sources responsible for cosmi…
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…
A multi-dimensional numerical scheme for two-fluid Relativistic MHD
Maxim Barkov, Serguei S. Komissarov, Vitaly Korolev +1
The paper describes an explicit multi-dimensional numerical scheme for Special Relativistic Two-Fluid Magnetohydrodynamics of electron-positron plasma and a suit of test problems.…
The beaming pattern of External Compton Emission from relativistic outflows
S. R. Kelner, E. Lefa, F. M. Rieger +1
The beaming pattern of radiation emitted by a relativistically moving source like jets in microquasars, AGN and GRBs, is a key issue for understanding of acceleration and radiation…
Nonthermal radiation of young supernova remnants: the case of Cas A
V. N. Zirakashvili, F. A. Aharonian, R. Yang +2
The processes responsible for the broad-band radiation of the young supernova remnant Cas A are explored using a new code which is designed for a detailed treatment of the diffusiv…
Radiative damping and emission signatures of strong superluminal waves in pulsar winds
Iwona Mochol, John G. Kirk
We analyse the damping by radiation reaction and by Compton drag of strong, superluminal electromagnetic waves in the context of pulsar winds. The associated radiation signature is…

Ruo-Yu Liu, Andrew Taylor, Martin Lemoine +2
The joint analysis of anisotropy signals and chemical composition of ultra-high energy cosmic rays offers strong potential for shedding light on the sources of these particles. Fol…
