H.E.S.S. (High Energy Stereoscopic System), which is designed to detect TeV gamma-rays, is a system of four Imaging Atmospheric Cherenkov Telescopes situated in Namibia. The system has been shown to be very successful in detecting and observing galactic and extra-galactic TeV sources. In order to explore the highest energy end of GRB spectra, a GRB observing program has been established in the H.E.S.S. collaboration. Here we introduce our GRB observing program and report on its current status.
The High Energy Stereoscopic System (H.E.S.S.) has been searching for counterparts of Gamma Ray Bursts (GRBs) for many years. In 2012 the system was upgraded with a fifth $28$ m diameter telescope (CT5) which is equipped with faster motors for rapid
Very high energy (VHE; >100 GeV) gamma-ray observations of PG 1553+113 were made with the High Energy Stereoscopic System (HESS) in 2005 and 2006. A strong signal, ~10 standard deviations, is detected by HESS during the 2 years of observations (24.8
We give a short review of gamma-ray burst (GRB) observations with the Konus-WIND (KW) experiment, which has been providing a continuous all-sky coverage in the 20 keV-15 MeV band during the period from 1994 to present. The recent results include a sy
HESS J0632+057 is one of only two unidentified high energy gamma-ray sources which appear to be point-like in nature. It is possibly associated with the massive star MWC 148 and has been suggested to resemble known TeV binary systems like LS I +61 30
We present a new and deep analysis of the pulsar wind nebula (PWN) HESS,J1825--137 with a comprehensive data set of almost 400 hours taken with the H.E.S.S. array between 2004 and 2016. The large amount of data, and the inclusion of low-threshold H.E
