On the detection potential of blazar flares for current neutrino telescopes
(IOP Publishers, 2020)
Blazar jets are extreme environments, in which relativistic proton interactions with an ultraviolet photon field could give rise to photopion production. High-confidence associations of individual high-energy neutrinos ...
Event reconstruction for KM3NeT/ORCA using convolutional neural networks
(IOP Publishing, 2020)
The KM3NeT research infrastructure is currently under construction at two locations in the Mediterranean Sea. The KM3NeT/ORCA water-Cherenkov neutrino detector off the French coast will instrument several megatons of ...
The fourth catalog of active galactic nuclei detected by the Fermi large area telescope
(IOP, 2020)
The fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) between 2008 August 4 and 2016 August 2 contains $2863$ objects located at high Galactic ...
gSeaGen: the KM3NeT GENIE-based code for neutrino telescopes
(Elsevier, 2020)
The gSeaGen code is a GENIE-based application developed to efficiently generate high statistics samples of events, induced by neutrino interactions, detectable in a neutrino telescope. The gSeaGen code is able to generate ...
Simultaneous observations of the blazar PKS 2155-304 from ultra-violet to TeV energies
(EDP Sciences, 2020)
Here we report the results of the first ever contemporaneous multi-wavelength observation campaign on the BL Lac object PKS 2155−304 involving Swift, NuSTAR, Fermi-LAT, and H.E.S.S. The use of these instruments allows us ...
Search for dark matter signals towards a selection of recently detected DES dwarf galaxy satellites of the Milky Way with HESS
(APS, 2020)
Dwarf spheroidal galaxy satellites of the Milky Way are prime targets for indirect detection of dark matter with gamma rays due to their proximity, high dark matter content, and absence of nonthermal emission processes. ...
Very high energy γ-ray emission from two blazars of unknown redshift and upper limits on their distance
(Oxford Univ Press, 2020)
We report on the detection of very high energy (VHE; E > 100 GeV) γ-ray emission from the BL Lac objects KUV 00311−1938 and PKS 1440−389 with the High Energy Stereoscopic System (H.E.S.S.). H.E.S.S. observations were ...
H.E.S.S. and Fermi-LAT observations of PSR B1259-63/LS 2883 during its 2014 and 2017 periastron passages
(EDP Sciences, 2020)
Context. PSR B1259–63/LS 2883 is a gamma-ray binary system consisting of a pulsar in an eccentric orbit around a bright Oe stellar-type companion star that features a dense circumstellar disc. The bright broad-band emission ...
Hard X-ray properties of radio-selected blazars
(EDP Sciences, 2020)
Context. Hard X-ray properties of beamed active galactic nuclei have been published in the 105-month Swift/BAT catalog, but there have not been any studies carried out so far on a well-defined, radio-selected sample of ...
Probing the magnetic field in the GW170817 outflow using HESS observations
(IOP Publishing, 2020)
The detection of the first electromagnetic counterpart to the binary neutron star (BNS) merger remnant GW170817 established the connection between short γ-ray bursts and BNS mergers. It also confirmed the forging of heavy ...
