Located at the Canary island of La Palma, MAGIC is the world-wide largest Imaging Atmospheric Cherenkov telescope. MAGIC-I has been in operation since 2004. Currently, two twin telescopes can take data in stereo mode. Both in single or stereo mode, the telescopes deliver a wealth of exciting physics results in the Very High Energy (VHE) region of

We present archival high-spatial-resolution VLA and VLBA data of the nuclei of seven of the nearest and brightest Seyfert galaxies in the Southern Hemisphere. At VLA resolution (~0.1arcsec), the nuclei of the Seyfert galaxies are unresolved, with the exception of MCG-5-23-16 and NGC7469, which show a core-jet structure. Three Seyfert nuclei are

Context. As a planet eclipses its parent star, a dark spot on the surface of the star may be occulted, causing a detectable variation in the light curve. Aims: We study these light curve variations during transits and infer the physical characteristics of the stellar spots. Methods: A total of 77 consecutive transit light curves of CoRoT-2 were

We present a catalogue of 1602 white-dwarf-main-sequence (WDMS) binaries from the spectroscopic Sloan Digital Sky Survey Data Release 6 (SDSS DR6). Among these, we identify 440 as new WDMS binaries. We select WDMS binary candidates by template fitting all 1.27 million DR6 spectra, using combined constraints in both χ2 and signal-to-noise ratio. In

We present photometry of nine cataclysmic variable stars identified by the Sloan Digital Sky Survey, aimed at measuring the orbital periods of these systems. Four of these objects show deep eclipses, from which we measure their orbital periods. The light curves of three of the eclipsing systems are also analysed using the lcurve code, and their
