H.E.S.S. is a system of Imaging Atmospheric Cherenkov Telescopes (IACTs) measuring cosmic gamma-rays with very high energies in Namibia. Extending the array with a fifth telescope with a mirror area of 600 m$^2$ leads to a lower energy threshold as well as an increased sensitivity of the system. Moreover, it is now the first IACT array consisting of telescopes with different sizes. Low-energetic gamma-rays detected by the telescopes can either be analyzed monoscopically, allowing for a lower threshold, or stereoscopically, using hybrid events only which leads to a better reconstruction performance. We present the status of the monoscopic analysis of H.E.S.S. II events. In order to cross-check the results, we use two independent analysis chains, based on different reconstruction methods. The first method uses the second moments of the cleaned camera image (Hillas parameters) in order to deduce the properties of the primary particle. The background discrimination of this method can be optimized with multi-variate analysis techniques. The second method is based on the comparison of the camera image with the results of a semi-analytical model of the air shower using a Loglikelihood-Maximization. We present the status of these analysis efforts and their respective performances. One of the chains has been applied on real data of the Crab Nebula. All results shown here have to be considered preliminary.
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiments sensitivity to lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with CT5, providing access to gamma-ray ene
H.E.S.S. is an array of five Imaging Atmospheric Cherenkov Telescopes (IACTs) located 1800 m above sea level in the Khomas Highland of Namibia and is sensitive to very-high-energy (VHE) gamma rays between tens of GeV to tens of TeV. The very-high bac
Gamma-ray bursts (GRBs) are some of the most energetic and exotic events in the Universe, however their behaviour at the highest energies (>10 GeV) is largely unknown. Although the Fermi-LAT space telescope has detected several GRBs in this energy ra
Cosmic particles hitting Earths moon produce radio emission via the Askaryan effect. If the resulting radio ns-pulse can be detected by radio telescopes, this technique potentially increases the available collective area for ZeV scale particles by se
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
