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. ...
