H.E.S.S. observations of the binary system PSR B1259-63/LS 2883 around the 2010/2011 periastron passage (2013)
Journal Article
Abramowski, A., Acero, F., Aharonian, F., Akhperjanian, A., Anton, G., Balenderan, S., …Zechlin, H. (2013). H.E.S.S. observations of the binary system PSR B1259-63/LS 2883 around the 2010/2011 periastron passage. Astronomy & Astrophysics, 551, Article A94. https://doi.org/10.1051/0004-6361/201220612

Aims. We present very high energy (VHE; E > 100 GeV) data from the γ-ray binary system PSR B1259-63/LS 2883 taken around its periastron passage on 15th of December 2010 with the High Energy Stereoscopic System (H.E.S.S.) of Cherenkov Telescopes. We a... Read More about H.E.S.S. observations of the binary system PSR B1259-63/LS 2883 around the 2010/2011 periastron passage.

Search for very-high-energy γ-ray emission from Galactic globular clusters with H.E.S.S (2013)
Journal Article
Abramowski, A., Acero, F., Aharonian, F., Akhperjanian, A., Anton, G., Balenderan, S., …Zechlin, H. (2013). Search for very-high-energy γ-ray emission from Galactic globular clusters with H.E.S.S. Astronomy & Astrophysics, 551, Article A26. https://doi.org/10.1051/0004-6361/201220719

Context. Globular clusters (GCs) are established emitters of high-energy (HE, 100 MeV < E < 100 GeV) γ-ray radiation which could originate from the cumulative emission of the numerous millisecond pulsars (msPSRs) in the clusters’ cores or from invers...

Introducing the CTA concept (2013)
Journal Article
Acharya, B., Actis, M., Aghajani, T., Agnetta, G., Aguilar, J., Aharonian, F., …Zychowski, P. (2013). Introducing the CTA concept. Astroparticle Physics, 43(SI), 3-18. https://doi.org/10.1016/j.astropartphys.2013.01.007

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to spa... Read More about Introducing the CTA concept.

Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S (2013)
Journal Article
Abramowski, A., Acero, F., Aharonian, F., Akhperjanian, A., Anton, G., Balenderan, S., …Zechlin, H. (2013). Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S. Astronomy & Astrophysics, 550, Article A4. https://doi.org/10.1051/0004-6361/201220355

The extragalactic background light (EBL) is the diffuse radiation with the second highest energy density in the Universe after the cosmic microwave background. The aim of this study is the measurement of the imprint of the EBL opacity to γ-rays on th...

Search for Photon-Linelike Signatures from Dark Matter Annihilations with H.E.S.S (2013)
Journal Article
Abramowski, A., Acero, F., Aharonian, F., Akhperjanian, A., Anton, G., Balenderan, S., …Zechlin, H. (2013). Search for Photon-Linelike Signatures from Dark Matter Annihilations with H.E.S.S. Physical Review Letters, 110(4), Article 041301. https://doi.org/10.1103/physrevlett.110.041301

Gamma-ray line signatures can be expected in the very-high-energy (Eγ>100  GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal would be readily distinguishable from astrophysical γ-ray sources that in m... Read More about Search for Photon-Linelike Signatures from Dark Matter Annihilations with H.E.S.S.
