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

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 infra-red source was identified in the galaxy NGC4993 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 next Ligo-Virgo observing run in 2019.

ENGRAVEr's mind under pressure - Dry run before Christmas

The ENGRAVE collaboration finished their first dry run in preparation for the LIGO/VIRGO engineering run ER13 starting on 14 December. With new gravitational wave detections on the horizon four ENGRAVE operations teams tested for the first time telescope triggers, data reduction step-by-step procedure and their observation strategies and capabilities. We would like to thank all participants for their efforts! ...

ENGRAVE awarded VLT Large Programme

ENGRAVE saw a successful start to its planned use of ESO’s Very Large Telescope with a substantial allocation of time in Period 102. ESO’s OPC awarded us time on UT1 to use NAC0 and FORS2, UT2 to employ X-SHOOTER and UT4 using HAWK-I and MUSE. ...
