H.E.S.S. observations of the 2021 periastron passage of PSR B1259-63/LS 2883
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +141
PSR B1259-63 is a gamma-ray binary system that hosts a pulsar in an eccentric orbit, with a 3.4 year period, around an O9.5Ve star. At orbital phases close to periastron passages,…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
Fires in the deep: The luminosity distribution of early-time gamma-ray-burst afterglows in light of the Gamow Explorer sensitivity requirements
D. A. Kann, N. E. White, G. Ghirlanda +58
Gamma-ray bursts (GRBs) are ideal probes of the Universe at high redshift (z > 5), pinpointing the locations of the earliest star-forming galaxies and providing bright backlights t…
Detection of extended gamma-ray emission around the Geminga pulsar with H.E.S.S
H. E. S. S. Collaboration, :, F. Aharonian +165
Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar was discovered by…
Probing the Non-thermal Emission Geometry of AR Sco via Optical Phase-Resolved Polarimetry
Louis du Plessis, Christo Venter, Zorawar Wadiasingh +4
AR Sco is a binary system that contains a white and red dwarf. The rotation rate of the white dwarf has been observed to slow down, analogous to rotation-powered radio pulsars; it…
Search for dark matter annihilation signals from the Galactic Center with the H.E.S.S. Inner Galaxy Survey
A. Montanari, E. Moulin, D. Malyshev
The presence of dark matter (DM) is suggested by a wealth of astrophysical and cosmological measurements. However, its underlying nature is yet unknown. Among the most promising ca…
