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.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos

The Dark Energy Spectroscopic Instrument (DESI), a new instrument designed to accurately map the Universe, begins its final testing stage.

Researchers from the Institut de Física d'Altes Energies (IFAE), the Institute of Space Science (ICE, CSIC), the Institute of Space Studies of Catalonia (IEEC), the Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT) and the Instituto de Física Teórica (IFT, UAM-CSIC) participate in the project.

Virgo and LIGO join forces for a new year-long signal hunt

The Virgo and LIGO detectors are ready to start the new Observing run called O3, lasting a whole year. The hunt for gravitational waves is set to start on April 1st when the European Virgo detector, based in Italy at the European Gravitational Observatory (EGO), and the LIGO twin detectors, located in the state of Washington and Louisiana (USA), will start to take data becoming together the most sensitive gravitational wave observatory to date. During a one-year period, the LIGO and Virgo Collaborations will register science data continuously, and the three detectors will operate as a global observatory.

IFAE joins the VIRGO collaboration

The detection of Gravitational Waves (GWs) from a black hole (BH) binary merger by LIGO in 2015 is a milestone that represents the beginning of a new era in the exploration of the universe. Shortly after the addition of the VIRGO antenna into the network lead to the detection of the neutron star (NS) binary merger that could be followed in electromagnetic signals, and thus represents the beginning of multi-messenger astronomy. These events have radically changed the stage for several areas of physics, from astrophysics to particle physics.

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.
