ENGRAVE - Electromagnetic counterparts of gravitational wave sources at the Very Large Telescope

ENGRAVE is a international collaboration bringing together astronomers who use the ESO facilities to research gravitational wave events. It collects over 250 researchers, with both theoretical and observational expertise.


ENGRAVE - Electromagnetic counterparts of gravitational wave sources at the Very Large Telescope

ESO/A.J. Levan, N.R. Tanvir

On 17th August 2017, a gravitational wave signal lasting for more than 50 seconds was discovered by the Ligo-Virgo Science Collaboration and just 1.7 seconds later a short burst of gamma rays was detected by the Fermi and INTEGRAL satellites. A new optical and infrared source was identified in the galaxy NGC 4993 that was unlike any other transient ever reported. This was AT2017gfo, a kilonova from the merger of two neutron stars, powered by the radioactive decay of r-processed heavy elements. The European Southern Observatory’s telescopes played a central role in the discovery and we have formed ENGRAVE to use ESO’s powerful resources during the ongoing LIGO-Virgo observing run in 2019-2020.

ENGRAVE scientists awarded JWST time

In the life of professional astronomers, it is a nail-biting moment when the results from a call for proposals are announced. But March 30 was a very special day, as the Space Telescope Space Institute announced the allocation for the first year (Cycle 1) of the James Webb Space Telescope (JWST). This is the forthcoming next-generation space telescope, due to be launched later this year, on October 31st, and a cornerstone mission in the history of astronomy. ...

2nd ENGRAVE collaboration meeting

The second ENGRAVE all-hands meeting was held from 12-14th November 2018 at the INAF Capodimonte Astronomical Observatory, Naples, under beautiful blue skies and the shadow of Vesuvius. We thank the local organisers led by Maria Teresa Boticella, Aniello Grado and their team of Fabio Ragosta, Pietro Schipani, A. Di Dato, M.T. Fulco, A. Maiorica and R. Aiello. ENGRAVE thanks GRAWITA and Instituto Nazionale di Astrofisica (INAF) for their generous support of the meeting, and to the Director of Capodimonte Marcella Marconi for hosting us. ...
