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
Aharonian, F., Akhperjanian, A., Bazer-Bachi, A., Beilicke, M., Benbow, W., Berge, D., …Wagner, S. (2005). 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..

Multi-wavelength observations of PKS 2155-304 with HESS (2005)
Journal Article
Aharonian, F., Akhperjanian, A., Bazer-Bachi, A., Beilicke, M., Benbow, W., Berge, D., …Wagner, S. (2005). Multi-wavelength observations of PKS 2155-304 with HESS. Astronomy & Astrophysics, 442(3), 895-907. https://doi.org/10.1051/0004-6361%3A20053353

The High Energy Stereoscopic System (HESS) has observed the high-frequency peaked BL Lac object PKS 2155- 304 in 2003 between October 19 and November 26 in Very High Energy (VHE) gamma-rays (E >= 160 GeV for these observations). Observations were car... Read More about Multi-wavelength observations of PKS 2155-304 with HESS.

Observations of selected AGN with HESS (2005)
Journal Article

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...

Discovery of the binary pulsar PSR B1259-63 in very-high-energy gamma rays around periastron with HESS. (2005)
Journal Article
Aharonian, F., Akhperjanian, A., Aye, K., Bazer-Bachi, A., Beilicke, M., Benbow, W., …Wagner, S. (2005). Discovery of the binary pulsar PSR B1259-63 in very-high-energy gamma rays around periastron with HESS. Astronomy & Astrophysics, 442(1), 1-10. https://doi.org/10.1051/0004-6361%3A20052983

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..

Discovery of very high energy gamma rays associated with an x-ray binary (2005)
Journal Article
Aharonian, F., Akhperjanian, A., Aye, K., Bazer-Bachi, A., Beilicke, M., Benbow, W., …Wagner, S. (2005). Discovery of very high energy gamma rays associated with an x-ray binary. Science, 309(5735), 746-749. https://doi.org/10.1126/science.1113764

X-ray binaries are composed of a normal star in orbit around a neutron star or stellar-mass black hole. Radio and x-ray observations have led to the presumption that some x-ray binaries called microquasars behave as scaled-down active galactic nuclei...
