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.

ATLAS observes elusive Higgs boson decay to a pair of bottom quarks

The ATLAS Collaboration at CERN's Large Hadron Collider (LHC) has – at long last – observed the Higgs boson decaying into a pair of bottom (b) quarks. This elusive interaction is predicted to make up almost 60% of the Higgs boson decays and is thus primarily responsible for the Higgs natural width. Yet it took over six years after the 2012 discovery of the Higgs boson to accomplish this observation.

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.

ATLAS observes interaction between Higgs boson and top quark, the heaviest known elementary particle

The ATLAS Collaboration at CERN has announced the observation of Higgs bosons produced together with a top-quark pair. Observing this extremely rare process is a significant milestone for the field of High-Energy Physics. It allows physicists to test critical parameters of the Higgs mechanism in the Standard Model of particle physics.

Since 2011 the IFAE-ATLAS group has led searches for ttH production, focusing on the dominant Higgs boson decay mode into a bottom-antibottom-quark pair (H->bb)
