H.E.S.S. searches for TeV gamma rays associated to high-energy neutrinos

Fabian Schüssler, Halim Ashkar, Michael Backes +12

The detection of an astrophysical flux of high-energy neutrinos by IceCube is a major step forward in the search for the origin of cosmic rays, as this emission is expected to orig…

Searches for counterparts of gravitational waves at very high energies with H.E.S.S

Monica Seglar-Arroyo, Halim Ashkar, Simon Bonnefoy +10

The recent milestones in multi-messenger astronomy have opened new ways to study the Unverse. The unprecedented gravitational wave (GW) follow-up campaigns established the power th…

Constraints on the emission region of 3C 279 during strong flares in 2014 and 2015 through VHE gamma-ray observations with H.E.S.S

H. E. S. S. Collaboration, H. Abdalla, R. Adam +224

The flat spectrum radio quasar 3C 279 is known to exhibit pronounced variability in the high-energy (MeVGeV) -ray band, which is continuously monitored with Fer…

Upper Limits on Very-High-Energy Gamma-ray Emission from Core-Collapse Supernovae Observed with H.E.S.S

H. E. S. S. Collaboration, :, H. Abdalla +225

Young core-collapse supernovae with dense-wind progenitors may be able to accelerate cosmic-ray hadrons beyond the knee of the cosmic-ray spectrum, and this may result in measurabl…

The 2014 TeV Gamma-ray Flare of Mrk 501 Seen with H.E.S.S.: Temporal and Spectral Constraints on Lorentz Invariance Violation

H. E. S. S. Collaboration, :, H. Abdalla +232

The blazar Mrk 501 (z=0.034) was observed at very-high-energy (VHE, ~GeV) gamma-ray wavelengths during a bright flare on the night of 2014 June 23-24 (MJD 56832) with…
