Aims.We present results from deep observations of the Galactic shell-type supernova remnant (SNR) RX J1713.7-3946 (also known as G347.3-0.5 ) conducted with the complete HESS array in 2004. Methods.Detailed morphological and spatially resolved spectr... Read More about A detailed spectral and morphological study of the gamma-ray supernovaremnant RX J1713.7-3946 with HESS.

A low level of extragalactic background light as revealed by big gamma-rays from blazars (2006)
Journal Article
Aharonian, F., Akhperjanian, A., Bazer-Bachi, A., Beilicke, M., Benbow, W., Berge, D., …Wagner, S. (2006). A low level of extragalactic background light as revealed by big gamma-rays from blazars. Nature, 440(7087), 1018-1021. https://doi.org/10.1038/nature04680

The diffuse extragalactic background light consists of the sum of the starlight emitted by galaxies through the history of the Universe, and it could also have an important contribution from the 'first stars', which may have formed before galaxy form...

A possible association of the new VHE γ-ray source HESS J1825–137 with the pulsar wind nebula G 18.0–0.7. (2005)
Journal Article

A possible association of the new VHE γ-ray source HESS J1825–137 with the pulsar wind nebula G 18.0–0.7. Astronomy & Astrophysics, 442(3), L25-L29. https://doi.org/10.1051/0004-6361%3A200500180

We report on a possible association of the recently discovered very high-energy γ-ray source HESS J1825–137 with the pulsar wind nebula (commonly referred to as G 18.0–0.7) of the 2.1 × 104 year old Vela-like pulsar PSR B1823–13. HESS J1825–137 was d... Read More about A possible association of the new VHE γ-ray source HESS J1825–137 with the pulsar wind nebula G 18.0–0.7..

A search for very high energy gamma-ray emission from the starburstgalaxy NGC253 with HESS (2005)
Journal Article
Aharonian, F., Akhperjanian, A., Bazer-Bachi, A., Beilicke, M., Benbow, W., Berge, D., …Wagner, S. (2005). A search for very high energy gamma-ray emission from the starburstgalaxy NGC253 with HESS. Astronomy & Astrophysics, 442(1), 177-183. https://doi.org/10.1051/0004-6361%3A20053521

We present the result of 28 h of observations of the nearby starburst galaxy NGC 253 with the HESS$\,$detector in 2003. We find no evidence for very high energy $\gamma$-ray emission from this object. Gamma-ray emission above 400 GeV from NGC 253 had...

We report the discovery of very-high-energy (VHE) $\gamma$-ray emission of the binary system PSR B1259-63 / SS 2883 of a radio pulsar orbiting a massive, luminous Be star in a highly eccentric orbit. The observations around the 2004 periastron passag... Read More about Discovery of the binary pulsar PSR B1259-63 in very-high-energy gamma rays around periastron with HESS..
