H.E.S.S. Observations of PKS 2155-304
The H. E. S. S. Collaboration, :, F. Aharonian
The high-frequency peaked BL Lac PKS 2155-304 at redshift z=0.117 has been detected with high significance (~45 sigma) at energies greater than 160 GeV, using the H.E.S.S. stereosc…
High-energy particle acceleration in the shell of a supernova remnant
H. E. S. S. Collaboration, :, F. Aharonian
A significant fraction of the energy density of the interstellar medium is in the form of high-energy charged particles (cosmic rays). The origin of these particles remains uncerta…
TeV -radiation from Dark Matter annihilation in the Galactic center
D. Horns
Recent observations of the Galactic center with ground based gamma-ray instruments have revealed a TeV (10 eV) gamma-ray signal consistent with the position of Sgr A*. The d…
Very high energy gamma rays from the direction of Sagittarius A*
H. E. S. S. Collaboration, :, F. Aharonian
We report the detection of a point-like source of very high energy (VHE) gamma-rays coincident within 1' of Sgr A*, obtained with the H.E.S.S. array of Cherenkov telescopes. The ga…
The Crab nebula: Linking MeV synchrotron and 50 TeV inverse Compton photons
D. Horns, F. A. Aharonian
Pulsar wind driven synchrotron nebulae are offering a unique view on the connection of the pulsar wind and the surrounding medium. The Crab nebula is particularly well suited for d…
The Crab Nebula and Pulsar between 500 GeV and 80 TeV: Observations with the HEGRA stereoscopic air Cherenkov telescopes
F. Aharonian et al.
The Crab supernova remnant has been observed regularly with the stereoscopic system of 5 imaging air Cherenkov telescopes that was part of the High Energy Gamma Ray Astronomy (HEGR…
Calibration of cameras of the H.E.S.S. detector
H. E. S. S. Collaboration, :, F. Aharonian
H.E.S.S. - the High Energy Stereoscopic System- is a new system of large atmospheric Cherenkov telescopes for GeV/TeV astronomy. Each of the four telescopes of 107 m^2 mirror area…
Observations of 54 Active Galactic Nuclei with the HEGRA System of Cherenkov Telescopes
The HEGRA Collaboration, F. Aharonian, A. Akhperjanian +1
A sample of 54 selected Active Galactic Nuclei (AGN) has been observed with the HEGRA stereoscopic system of Cherenkov Telescopes between 1996 and 2002 in the TeV energy regime. Th…
