The variety of extreme blazars in the AstroSat view
Pranjupriya Goswami, Michael Zacharias, Andreas Zech +3
Extreme blazars have exceptionally hard intrinsic X-ray/TeV spectra and extreme peak energies in their spectral energy distribution (SED). Observational evidence suggests that the…
Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts
The H. E. S. S. Collaboration, :, F. Aharonian +178
Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…
Probing orbital parameters of gamma-ray binaries with TeV light curves
Iurii Sushch, Brian van Soelen
Gamma-ray binaries are binary systems where the energy flux peaks in the gamma-ray energy band. They harbour a compact object (a neutron star or a black hole) orbiting around a mas…
Gamma-ray detection of newly discovered Ancora SNR: G288.8-6.3
Christopher Burger-Scheidlin, Robert Brose, Jonathan Mackey +5
The supernova remnant (SNR) G288.8-6.3 was recently discovered as a faint radio shell at large Galactic latitude using observations with ASKAP in the EMU survey. Here, we make the…
The peculiar new state of the blazar PKS 1510-089
H. M. Schutte, M. Zacharias, M. Böttcher +4
Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…
Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749
T. Wach, A. M. W. Mitchell, V. Joshi +1
HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind neb…
