The MAGIC telescopes are a stereoscopic systemof two 17m mirror diameter Cherenkov telescopes for gamma-ray observations, in operation since many years on the island ofLa Palma at the Observatorio del Roque de los Muchachos.A new installation allows us to use those telescopes as opticalintensity interferometer which enables us to measure the size

Axion detection would be one of the most exciting moments in the entire history of science. This hypothetical particle can simultaneously explain two fundamental problems in Modern Physics: the mystery of dark matter and the CP problem of the strong interaction. In this talk, I will provide an overview of the status for the search for axions and I

The improvement on the Imaging Air Cherenkov Technique led to the discovery of a new class of compact binaries: the gamma-ray binaries. This small class consist of only five members, all of them composed by a massive star and a compact object. The nature of the compact object is unknown for all of them but PSR B1259-63, which contains a pulsar. It
