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…

Monte Carlo studies for the optimisation of the Cherenkov Telescope Array layout

A. Acharyya, I. Agudo, E. O. Angüner +467

The Cherenkov Telescope Array (CTA) is the major next-generation observatory for ground-based very-high-energy gamma-ray astronomy. It will improve the sensitivity of current groun…

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…

H.E.S.S. limits on line-like dark matter signatures in the 100 GeV to 2 TeV energy range close to the Galactic Centre

H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +246

A search for dark matter line-like signals was performed in the vicinity of the Galactic Centre by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likeliho…

Fermi-LAT Search for Pulsar Wind Nebulae around gamma-ray Pulsars

The Fermi LAT Collaboration, Pulsar Timing Consortium

The high sensitivity of the Fermi-LAT (Large Area Telescope) offers the first opportunity to study faint and extended GeV sources such as pulsar wind nebulae (PWNe). After one year…
