A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane

Zhen Cao, Felix Aharonian, Yunxiang Bai +312

Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes,…

Towards the second H.E.S.S. Galactic plane catalogue

Q. Remy

The H.E.S.S. Galactic Plane Survey (HGPS), carried out between 2004 and 2013, is the most extensive survey of our Galaxy at very-high energies that covers the southern sky. Since t…

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…
