Cosmic Cataclysm allows precise test of General Relativity

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies [1, 2]. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is constant in vacuum – and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein's theory of General Relativity. The study has now been published in Physical Review Letters [3].

Breaking the limits: discovery of the highest-energy photons from a gamma-ray burst

Gamma-ray bursts (GRBs) are brief and extremely powerful cosmic explosions, suddenly appearing in the sky, about once per day. They are thought to result from the collapse of massive stars or the merging of neutron stars in distant galaxies. They commence with an initial, very bright flash, called the prompt emission, with a duration ranging from a fraction of a second to hundreds of seconds. The prompt emission is accompanied by the so-called afterglow, a less brighter but longer-lasting emission over a broad range of wavelengths that fades with time. The first GRB detected by the MAGIC telescopes, known as GRB 190114C, reveals for the first time the highest energy photons measured from these objects.

Cosmic fireworks from a new gamma-ray binary

A joint observational campaign with the MAGIC telescopes at the Observatorio del Roque de los Muchachos (Garafía, La Palma) and the VERITAS array at the Fred Lawrence Whipple Observatory (Tucson, Arizona), has detected a new source emitting very-high-energy gamma rays from an unusual system consisting of a massive star and a pulsar. The study has just been published in the prestigious Astrophysical Journal Letters.

MAGIC telescopes trace origin of a rare cosmic neutrino

For the first time, astrophysicists have localised the source of a cosmic neutrino originated outside of the Milky Way. With high probability, the neutrino comes from a blazar, an active black hole at the centre of a distant galaxy in the Orion constellation.

NOVEMBER 2014 - Black Hole Gamma-Ray Lightning


Black Hole Gamma-Ray Lightning

(Versió en català al final)

(Versión en español al final)

The MAGIC telescopes at La Palma have recorded the fastest gamma-ray flares seen to date, produced in the vicinity of a super-massive black hole. The scientists explain this phenomenon by a mechanism similar to that producing lightning in a storm. This result, with an important Spanish contribution, is published today in Science.

APRIL 2010 - First source discovered with MAGIC II

The MAGIC Collaboration reports the discovery of VHE gamma-ray emission from the new source MAGIC J0317+413. The source was in the field of view of the MAGIC telescopes between October 2009 and February 2010.
