    Flux Upper Limit on Gamma-Ray Emission by GRB 050713a from MAGIC Telescope Observations
    The long-duration γ-ray burst GRB 050713a was observed by the MAGIC Telescope 40 s after the burst onset and followed up for 37 minutes, until twilight. The...

    Galactic Populations of Radio and Gamma-Ray Pulsars in the Polar Cap Model
    We simulate the characteristics of the Galactic population of radio and γ-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially...

    Gamma rays from Young Stellar Objects
    In the last years star-forming regions and massive protostars have been suggested to be gamma-ray emitters. Isolated massive protostars present powerful...

    Gamma-ray bursts as a tool to unveil obscured star-forming galaxies
    Long Gamma-Ray Bursts are flashes of high-energy radiation and are linked to the death of massive stars. I will first summarize the main aspects of GRB...

    Gamma-ray Excess from a Stacked Sample of High- and Intermediate-frequency Peaked Blazars Observed with the MAGIC Telescope
    Between 2004 and 2009, a sample of 28 X-ray selected high- and intermediate-frequency peaked blazars with an X-ray flux larger than 2 μJy at 1 keV in the...

    Gamma-ray flaring activity of NGC1275 in 2016-2017 measured by MAGIC
    We report on the detection of flaring activity from the Fanaroff-Riley I radio galaxy NGC 1275 in very-high-energy (VHE, E > 100 GeV) gamma rays with the Major...

    Gamma-ray line emission from OB associations and young open clusters. I. Evolutionary synthesis models
    We have developed a new diagnostic tool for the study of gamma-ray emission lines from radioactive isotopes (such as 26Al and 60Fe) in conjunction with other...
