MAGIC observations of the giant radio galaxy M87 in a low emission state between 2005 and 2007
We present the results of a long M87 monitoring campaign in very high energy $gamma$-rays with the MAGIC-I Cherenkov telescope. A total of 150 hours of data was...
MAGIC is built to perform observations of prompt and early afterglow emission from Gamma-Ray Bursts (GRBs) above 25 GeV. The instrument is designed to have the...
MAGIC upper limits on the high energy emission from GRBs
During its first observation cycle, between April 2005 and March 2006, the MAGIC telescope was able to observe nine different GRB events since their early...
MAGIC upper limits on the Very High Energy emission from GRBs
Since the beginning of its operation in April 2005, the MAGIC telescope was able to observe ten different GRB events since their early beginning, even while the...
Magnetic activity and its variability in the Sun and solar-like stars
The light curves of solar-like stars provide information on stellar rotation and magnetic activity thanks to active-region crossings. In this work, we...
Magnetic activity evolution on the main sequence from the Kepler observations
The evolution of rotation and magnetic activity of solar-like stars is key to improve our knowledge of stars (e.g. ages). Several spectroscopic surveys have...
Magnetic activity of red giants: linking chromospheric indicators, oscillations amplitude, and tidal interactions
According to dynamo theory, stars with convective envelopes efficiently generate surface magnetic fields, which manifest as magnetic activity in the form of...
