A team of astrophysicists from the Institut de Recherche en Astrophysique et Planétologie of Toulouse, the Laboratoire d’Astrophysique of Marseille and the Centre de Recherche Astrophysique of Lyon, have just discovered a giant […]
MOSAIC at the ELT: A Gigantic Step into the Deep Universe
The MOSAIC multi-object spectrograph will be the workhorse instrument for the future Extremely Large Telescope (ELT), the biggest visible/infrared telescope in the world. It will be the world-leading multi-object spectrograph […]
Optical characterization by IRAP astrophysicists of the kilonova associated with the gravitational wave event that occured on 17th August 2017
A gravitational wave event has been detected by the LIGO/Virgo gravitational wave observatories on the 17th August 2017. It quickly turned out that the signal corresponded to the fusion of […]
Discovery of the simultaneous emission of a gravitational wave and of gamma photons by a binary system of coalescing neutron stars
For the first time, a gravitational wave (GW170817) was detected simultaneously (within 2 seconds) with a photon emission in the form of a short-lived gamma ray burst (GRB170817A). The gravitational […]
