Contribution

MAGIC is one of the main present detectors for performing ground-based observations of VHE gamma-ray sources. It consists of two 17m diameter Imaging Atmospheric Cherenkov telescopes. The telescopes are located at 2200 m a.s.l. at the Roque de los Muchachos, on the Canary island of la Palma, Spain. They are designed to observe gamma rays with energies above ~50 GeV. The system recently...

Contribution

During the evolution of sunspots, the umbral region is sometimes divided into two or more parts by structures called light bridges. The kinematics and magnetic properties of light bridges are still not well understood and high resolution observations can contribute to clarify many of these properties. High spatial and spectral resolution data of the solar photosphere were acquired by the...
