Optical spectroscopy of the VHE flat-spectrum radio quasar PKS 0903-57
E. Kasai, P. Goldoni, C. Boisson +5
We report new optical spectroscopic results for the gamma-ray blazar PKS~090357. The optical properties of this source have historically been complicated to establish, due to a…
CtaAgnVar : a Pipeline for Variability Studies with the Cherenkov Telescope Array Observatory
G. Grolleron, J. -P. Lenain, J. Biteau +2
Blazars are active galactic nuclei whose relativistic jet points toward the observer, accelerating particles that radiate across the electromagnetic spectrum. Characterizing their…
H.E.S.S. detection of the PSR J0855-4644 nebula
F. Aharonian, H. Ashkar, M. Backes +131
HESS J0852-463 is a TeV γ-ray source located in the Galactic plane. The region consists of a supernova remnant (SNR, RX J0852.0-4622) with a shell-like morphology, commonly referre…
Prompt Searches for Very-High-Energy γ-Ray Counterparts to IceCube Astrophysical Neutrino Alerts
J. Abhir, A. Biland, K. Brand +817
The search for sources of high-energy astrophysical neutrinos can be significantly advanced through a multi-messenger approach, which seeks to detect the gamma rays that accompany…
Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr
A. Acharyya, F. Aharonian, H. Ashkar +131
Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
