Spectro-Polarimetric Observations of TeV Sources (SPOTS): First results
J. Barnard, B. van Soelen, I. P. van der Westhuizen +5
Blazars are jetted active galactic nuclei, with the jet aligned along the observer's line of sight. Their spectral energy distributions are dominated by non-thermal emission, with…
Multi-GeV Fermi-LAT Detection of PSR B1259-63
D. Malyshev, M. Chernyakova, A. Finn Gallagher +5
PSR B1259-63/LS 2883 is a classical gamma-ray binary detected from radio to TeV energies near periastron. Using over 17 years of Fermi-LAT observations, we report the first signifi…
Optical spectroscopy of blazars for the Cherenkov Telescope Array Observatory- IV
B. Rajput, P. Goldoni, W. Max-Moerbeck +17
Blazars, including BL Lacs and FSRQs, are the most luminous extragalactic γ-ray sources. They account for about 56% of the sources listed in the recent Fermi-LAT catalog (4FGL-DR4…
INTEGRAL/ISGRI post 2024-periastron view of PSR B1259-63
A. Kuzin, D. Malyshev, M. Chernyakova +2
PSR B1259-63/LS 2883 is a well-studied gamma-ray binary hosting a pulsar in a 3.4-year eccentric orbit around a Be-type star. Its non-thermal emission spans from radio to TeV energ…
