Cosmic Cataclysm allows precise test of General Relativity
July 9, 2020
The detection of a gamma ray burst by the MAGIC telescopes allows to study whether the speed of light in vacuum is a constant of nature. The results, published in the journal Physical Review Letters, show that photons of different energies emitted about 4.5 billion years ago reach Earth with a time difference of less than one minute, thus putting a limit on the hypothesis that the velocity of photons depends on their energy.
CTA Prototype LST-1 Detects Very High-Energy Emission from the Crab Pulsar
June 22, 2020
The first prototype of the Large Size Telescope (LST) of the Cherenkov Telescope Network (CTA), the LST-1, has detected the Crab Pulsar, the neutron star at the centre of the Crab Nebula. This observation certifies the proper functioning of this telescope, which is currently in the commissioning phase.
Breaking the limits: Discovery of the highest-energy photons from a gamma-ray burst
November 19, 2019
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.
Final Agreements Signed for CTA's Southern Hemisphere Site in Chile
December 20, 2018
On 19 December 2018, the Cherenkov Telescope Array Observatory (CTAO) and the European Southern Observatory (ESO) signed the final agreements needed for CTA’s southern hemisphere array to be hosted near ESO’s Paranal Observatory in Chile.
EU Particle Physics & Astronomy commit to the Research Data Revolution making the European Open Science Cloud a reality
December 3, 2018
The European project ESCAPE, funded with 16 million euros, will provide open data from astrophysics and particle physics large facilities, such as the LHC or the Cherenkov Telescope Array (CTA)
Cosmic fireworks from a new gamma-ray binary
November 13, 2018
A joint observational campaign with the MAGIC telescopes and the VERITAS array , has detected a new source emitting very-high-energy gamma rays from an unusual system consisting of a massive star and a pulsar
The First Telescope on a Cherenkov Telescope Array Site Makes its Debut
October 10, 2018
On Wednesday, 10 October 2018, more than 200 guests from around the world gathered on the northern array site of the Cherenkov Telescope Array (CTA) to celebrate the inauguration of the first prototype Large-Sized Telescope (LST).
MAGIC telescopes trace origin of a rare cosmic neutrino
July 12, 2018
For the first time, astrophysicists have localized the source of a high energy cosmic neutrino originating outside the Milky Way. It is highly likely that the neutrino comes from a blazar in the Orion constellation.
CTA Releases its Updated Science Case
September 27, 2017
The latest iteration of the Cherenkov Telescope Array's (CTA's) science case, Science with the Cherenkov Telescope Array, was made available today
