Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
H.E.S.S. and Fermi-LAT observations of PSR B1259-63/LS 2883 during its 2014 and 2017 periastron passages
H. E. S. S. Collaboration, H. Abdalla, R. Adam +222
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 di…
H.E.S.S. detection of very-high-energy gamma-ray emission from the quasar PKS 0736+017
H. E. S. S. Collaboration, :, H. Abdalla +225
Flat-spectrum radio-quasars (FSRQs) are rarely detected at very-high-energies (VHE; E>100 GeV) due to their low-frequency-peaked SEDs. At present, only 6 FSRQs are known to emit VH…
H.E.S.S. observations of the flaring gravitationally lensed galaxy PKS 1830-211
H. E. S. S. Collaboration, :, H. Abdalla +224
PKS 1830-211 is a known macrolensed quasar located at a redshift of z=2.5. Its high-energy gamma-ray emission has been detected with the Fermi-LAT instrument and evidence for lensi…
Measurement of the EBL spectral energy distribution using the VHE gamma-ray spectra of H.E.S.S. blazars
H. E. S. S. Collaboration, :, H. Abdalla +256
Very high-energy gamma-rays (VHE, E>100 GeV) propagating over cosmological distances can interact with the low-energy photons of the extragalactic background light (EBL) and produc…
Search for dark matter annihilations towards the inner Galactic halo from 10 years of observations with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdallah +245
The inner region of the Milky Way halo harbors a large amount of dark matter (DM). Given its proximity, it is one of the most promising targets to look for DM. We report on a searc…
