H.E.S.S. programme searching for VHE gamma rays associated with FRBs

F. Aharonian, A. Archaryya, J. Aschersleben +127

Fast Radio Bursts (FRBs) are highly energetic, extremely short-lived bursts of radio flashes. Despite extensive research, the exact cause of these outbursts remains speculative. Th…

Very-high-energy -ray emission from young massive star clusters in the Large Magellanic Cloud

F. Aharonian, F. Ait Benkhali, J. Aschersleben +129

The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant am…

Acceleration and transport of relativistic electrons in the jets of the microquasar SS 433

F. Aharonian, F. Ait Benkhali, J. Aschersleben +161

SS 433 is a microquasar, a stellar binary system with collimated relativistic jets. We observed SS 433 in gamma rays using the High Energy Stereoscopic System (H.E.S.S.), finding a…

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…

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…
