 2018-08-1313:35 [PUBDB-2018-02922] Report/Journal Article et al Measurement of the iron spectrum in cosmic rays by VERITAS [arXiv:1807.08010] Physical review / D 98(2), 022009 (2018) [10.1103/PhysRevD.98.022009]   We present a new measurement of the energy spectrum of iron nuclei in cosmic rays from 20 TeV to 500 TeV. The measurement makes use of a template-based analysis method, which, for the first time, is applied to the energy reconstruction of iron-induced air showers recorded by the VERITAS array of imaging atmospheric Cherenkov telescopes [...] OpenAccess: PDF PDF (PDFA); 2018-08-1313:24 [PUBDB-2018-02921] Journal Article et al The broad-band properties of the intermediate synchrotron peaked BL Lac S2 0109+22 from radio to VHE gamma-rays Monthly notices of the Royal Astronomical Society 480(1), 879 - 892 (2018) [10.1093/mnras/sty1753]   The Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes observed S2 0109+22 in 2015 July during its flaring activity in high-energy gamma-rays observed by Fermi-Large Area Telescope. We analyse the MAGIC data to characterize the very high energy (VHE) gamma-ray emission of S2 0109+22, which belongs to the subclass of intermediate synchrotron peak (ISP) BL Lacertae (BL Lac) objects.

It was soon determined that the neutrino direction was consistent with the location of the gamma-ray blazar TXS 0506+056 (3FGL J0509.4+0541), which was in an elevated gamma-ray emission state as measured by the Fermi satellite.

Studies exploring the classification of the source are converging toward its identification as an extreme synchrotron BL Lac object.

As the brightest region of diffuse γ-ray emission in the northern sky, the Cygnus region provides a promising area to probe the origins of cosmic rays.

The LAT was entering the South Atlantic Anomaly at the time of the LIGO/Virgo trigger ($t_{GW}$) and therefore cannot place constraints on the existence of high-energy (E > 100 MeV) emission associated with the moment of binary coalescence.

Extragalactic diffuse $\gamma$-rays from dark matter annihilation: revised prediction and full modelling uncertainties [arXiv:1711.08323; DESY-17-218] Recent high-energy data from Fermi-LAT on the diffuse γ-ray background have been used to set among the best constraints on annihilating TeV cold dark matter candidates. In order to assess the robustness of these limits, we revisit and update the calculation of the isotropic extragalactic γ-ray intensity from dark matter annihilation. [...] OpenAccess: PDF PDF (PDFA);
