MAGIC upper limits to the VHE gamma-ray flux of 3C454.3 in high emission state

H. Anderhub, S. Vercellone, I. Donnarumma +2

We report upper limits to the very high energy flux (E>100 GeV) of the flat spectrum radio quasar 3C454.3 (z=0.859) derived by the Cherenkov telescope MAGIC during the high states…

New Constraints on Hidden Photons using Very High Energy Gamma-Rays from the Crab Nebula

Hannes-Sebastian Zechlin, Dieter Horns, Javier Redondo

Extensions of the standard model of particle physics, in particular those based on string theory, often predict a new U(1) gauge symmetry in a hidden sector. The corresponding gaug…

Discovery of a very high energy gamma-ray signal from the 3C 66A/B region

MAGIC Collaboration, E. Aliu

The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…

Very-High-Energy Gamma Rays from a Distant Quasar: How Transparent Is the Universe?

MAGIC Collaboration, J. Albert

The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar R…

Periodic very high energy gamma-ray emission from LS I +61 303 observed with the MAGIC telescope

MAGIC Collaboration, J. Albert

The MAGIC collaboration has recently reported the discovery of gamma-ray emission from the binary system LS I +61 303 in the TeV energy region. Here we present new observational re…

Signatures of a hidden cosmic microwave background

Joerg Jaeckel, Javier Redondo, Andreas Ringwald

If there is a hidden photon -- i.e. a light abelian gauge boson in the hidden sector -- its kinetic mixing with the standard photon can produce a hidden cosmic microwave background…
