Gamma-ray bursts (GRBs) are explosive transient events occurring at cosmological distances, releasing a large amount of energy as electromagnetic radiation over...
MAGIC observations of MWC 656, the only known Be/BH system
Context. MWC 656 has recently been established as the first observationally detected high-mass X-ray binary system containing a Be star and a black hole (BH)...
MAGIC telescopes detect the first gamma-rays burst at very high energies
This ground-breaking achievement by MAGIC provides critical new insight for understanding the physical processes at work in the most powerful cosmic explosions...
MAGIC telescopes test the quantum structure of space-time
The detection of a gamma ray burst by the MAGIC telescopes at the Roque de los Muchachos Observatory allows us to study whether the speed of light in a vacuum...
Multiwavelength follow-up of a rare IceCube neutrino multiplet
On February 17, 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another...
Context. Blazars are variable sources on various timescales over a broad energy range spanning from radio to very high energy (>100 GeV, hereafter VHE). Mrk 501...
SAMUEL TING: “If we find complete agreement with the theory, we don’t learn anything”
“I still remember the surface of the Moon seen from the Teide Observatory”. He will never forget the image: Sharp, close up, and brilliant. It was the first...
Search for VHE gamma-ray emission from Geminga pulsar and nebula with the MAGIC telescopes
The Geminga pulsar, one of the brighest gamma-ray sources, is a promising candidate for emission of very-high-energy (VHE > 100 GeV) pulsed gamma rays. Also...
Star tracking for pointing determination of Imaging Atmospheric Cherenkov Telescopes. Application to the Large-Sized Telescope of the Cherenkov Telescope Array
We present a novel approach to the determination of the pointing of Imaging Atmospheric Cherenkov Telescopes (IACTs) using the trajectories of the stars in...
