Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge

A. Acharyya, F. Aharonian, H. Ashkar +130

Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…

Scrutinizing the 2020 multiwavelength outburst of PKS 0903-57 through observations with H.E.S.S

A. Acharyya, F. Aharonian, F. Ait Benkhali +138

The blazar PKS 0903-57 has recently been classified as a flat spectrum radio quasar at a redshift of . In March and April 2020, Fermi-LAT and AGILE reported tremendous ac…

Cosmic rays, gas and dust in the Central Molecular Zone I -- factors, cosmic-ray densities and dust opacities

H. X. Ren, Q. Remy, S. Ravikularaman +3

Our goal is to estimate the total gas mass in the direction of the Central Molecular Zone (CMZ), quantify the various uncertainties associated, and discuss the implications for the…

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…

Modelling of highly extended Gamma-ray emission around the Geminga Pulsar as detected with H.E.S.S

A. M. W. Mitchell, S. Caroff

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 has been detected…

Multiwavelength Observations of the Blazar PKS~0735+178 in Spatial and Temporal Coincidence with an Astrophysical Neutrino Candidate IceCube-211208A

M. Pohl, K. Mori

We report on multiwavelength target-of-opportunity observations of the blazar PKS 0735+178, located 2.2 degrees away from the best-fit position of the IceCube neutrino event 211208…
