    Clouds vs Cherenkov telescopes: problems and solutions.
    Very-high-energy (VHE >~100 GeV) gamma rays are absorbed in Earth's atmosphere and thus cannot be detected directly on Earth. Their fluxes are also typically...

    Combined searches for dark matter in dwarf spheroidal galaxies observed with the MAGIC telescopes, including new data from Coma Berenices and Draco
    Milky Way dwarf spheroidal galaxies (dSphs) are among the best candidates to search for signals of dark matter annihilation with Imaging Atmospheric Cherenkov...

    Constraining cosmic rays and magnetic fields in the Perseus galaxy cluster with TeV observations by the MAGIC telescopes
    Galaxy clusters are being assembled today in the most energetic phase of hierarchical structure formation which manifests itself in powerful shocks that...

    Constraining Lorentz Invariance Violation Using the Crab Pulsar Emission Observed up to TeV Energies by MAGIC
    Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non...

    Constraints on an Optical Afterglow and on Supernova Light Following the Short Burst GRB 050813
    We report early follow-up observations of the error box of the short burst GRB 050813 using the telescopes at Calar Alto and Observatorio Sierra Nevada...

    Constraints on axion-like particles with the Perseus Galaxy Cluster with MAGIC
    Axion-like particles (ALPs) are pseudo-Nambu-Goldstone bosons that emerge in various theories beyond the standard model. These particles can interact with high...

    Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
    Context. The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE...

    Constraints on the Steady and Pulsed Very High Energy Gamma-Ray Emission from Observations of PSR B1951+32/CTB 80 with the MAGIC Telescope
    We report on very high energy γ-ray observations with the MAGIC Telescope of the pulsar PSR B1951+32 and its associated nebula, CTB 80. Our data constrain the...

    Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy γ-rays
    Aims: The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) γ-ray emitter by MAGIC, is one of the few non-blazar active galactic...
