Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +195
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 stud…
Searching for WISPy Cold Dark Matter with a Dish Antenna
Dieter Horns, Joerg Jaeckel, Axel Lindner +3
The cold dark matter of the Universe may be comprised of very light and very weakly interacting particles, so-called WISPs. Two prominent examples are hidden photons and axion-like…
The effect of photon-axion-like particle conversions in galaxy clusters on very high energy γ-ray spectra
Manuel Meyer, Dieter Horns, Luca Maccione +3
Very high energy (VHE, energy >~ 100 GeV) γ-rays originating from extragalactic sources interact with low energy photons of background radiation fields and produce electron-positro…
The sensitivity of Cherenkov telescopes to dark matter and astrophysical anisotropies in the diffuse gamma-ray background
Joachim Ripken, Alessandro Cuoco, Hannes-S. Zechlin +2
In this article, the capability of present (H.E.S.S., MAGIC, VERITAS) and planned (CTA) ground-based Cherenkov telescope systems for detecting angular anisotropies in the diffuse g…
Revisiting the Indication for a low opacity Universe for very high energy gamma-rays
Manuel Meyer, Dieter Horns, Martin Raue
Very high energy (VHE, energy >~ 100 GeV) γ-rays undergo pair production with photons of the extragalactic background light (EBL). Thus, the intrinsic γ-ray flux of cosmological so…
Astrophysical searches for a hidden-photon signal in the radio regime
A. P. Lobanov, H. -S. Zechlin, D. Horns
Common extensions of the Standard Model of particle physics predict the existence of a "hidden" sector that comprises particles with a vanishing or very weak coupling to particles…
