VHE Gamma-ray sources at the resolution limit of H.E.S.S
Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät, 131 pp. (2015) [10.18452/17517] = Humboldt Universität, Dissertation, 2015  GO
Very-high-energy (VHE)γ-ray astronomy deals with the ground-based detection of pho-tons with energies of a few tens of GeV to∼100 TeV by employing the Imaging Air Cherenkov Technique (IACT). This method uses the atmosphere as a detector for VHE γ-rays, exploiting that photons in that energy range produce particle showers by inter-acting with atmospheric particles. [...]

Pulsar wind nebulae at high energies : A diverse population and exceptional twins
142 pp. (2014) [10.3204/PUBDB-2017-11596] = Universität Potsdam, Dissertation, 2014  GO
Pulsar wind nebulae (PWNe) are the most abundant TeV $\gamma$-ray emitters in the Milky Way. The radiative emission of these objects is powered by fast-rotating pulsars, which donateparts of their rotational energy into winds of relativistic particles. [...]

The mystery of the origin of cosmic rays has been tackled for more than hundred years and is still not solved. Cosmic rays are detected with energies spanning more than 10 orders of magnitude and reaching energies up to ~ 10$^{21}$eV, far higher than any man-made accelerator can reach. [...]

Measurement of the EBL Spectral Energy Distribution Using the VHE $\gamma$-ray Spectra of H.E.S.S. Blazars
[arXiv:1707.06090] ddc:520
Very high-energy gamma-rays (VHE, E>100 GeV) propagating over cosmological distances can interact with the low-energy photons of the extragalactic background light (EBL) and produce electron-positron pairs. The transparency of the universe to VHE gamma-rays is then directly related to the spectral energy distribution (SED) of the EBL. [...]

Extended VHE $\gamma$-Ray Emission Towards SGR1806-20, LBV1806-20, and Stellar Cluster Cl*1806-20
[arXiv:1606.05404] ddc:520
Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) gamma-ray source towards the luminous blue variable candidate LBV1806-20, massive stellar cluster Cl*1806-20, and magnetar SGR1806-20. The new VHE source, HESSJ1808-204, was detected at a statistical significance of >6sigma (post-trial) with a photon flux normalisation $(2.9 \pm 0.4_{\rm stat} \pm 0.5_{\rm sys})\times 10^{-13}$\,ph\,cm$^{-2}$\,s$^{-1}$\,TeV$^{-1}$ at 1TeV and a power-law photon index of $2.3\pm0.2_{\rm stat}\pm 0.3_{\rm sys}$.

Radio Observations of the Region Around the Pulsar Wind Nebula HESS J1303−631 with ATCA
[arXiv:1706.05891] ddc:520
Radio observations of the region surrounding PSR J1301−6305 at 5.5 GHz and 7.5 GHz were conducted with ATCA on September 5, 2013. The observations were dedicated to the search of the radio counterpart of the evolved pulsar wind nebula (PWN) HESS J1303−631, which has been detected in X-rays and GeV–TeV γ-rays [...]
