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 ...
Multifrequency observations of the candidate neutrino-emitting blazar BZB J0955+3551
(IOP Publishing, 2020)
The recent spatial and temporal coincidence of the blazar TXS 0506+056 with the IceCube-detected neutrino event IC-170922A has opened up a realm of multimessenger astronomy with blazar jets as a plausible site of cosmic-ray ...
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 ...
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. ...
Radio afterglows of very high-energy gamma-ray bursts 190829A and 180720B
(Oxford Univ Press, 2020)
We present high-cadence multifrequency radio observations of the long gamma-ray burst (GRB) 190829A, which was detected at photon energies above 100 GeV by the High Energy Stereoscopic System (H.E.S.S.). Observations with ...
IceCube neutrino generated in a jet-jet collision in TXS 0506+056?
(Fabrizio Serra, 2020)
The IceCube event IceCube-170922A appears to originate from the BL Lac object TXS 0506+056. Despite many other BL Lac objects showing similar properties as TXS
0506+056, such as multiwavelength variability or a curved ...
H.E.S.S. detection of very high-energy γ-ray emission from the quasar PKS 0736+017
(EDP Sciences, 2020)
Context. Flat-spectrum radio-quasars (FSRQs) are rarely detected at very high energies (E ≥ 100 GeV) due to their low-frequency-peaked spectral
energy distributions. At present, only six FSRQs are known to emit very ...
First detection of the Crab Nebula at TeV energies with a Cherenkov telescope in a dual-mirror Schwarzschild-Couder configuration: the ASTRI-Horn telescope
(EDP Sciences, 2020)
We report on the first detection of very high-energy gamma-ray emission from the Crab Nebula by a Cherenkov telescope in dual-mirror
Schwarzschild-Couder (SC) configuration. This result has been achieved by means of the ...
