The needle and the haystack 07 February 2020
No firm electromagnetic counterpart of the first black hole / neutron star merger has been found by ENGRAVE. But the hunt continues! Read More ›

2nd ENGRAVE collaboration meeting 15 November 2019
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. Read More ›

The mystery of AT 2019osy 24 September 2019
While searching for a counterpart to the gravitational wave event from August 14 (S190814bv), astronomers using the ASKAP telescope discovered an unusual transient in the radio band: AT 2019osy. Its nature is unclear, but its location within a galaxy and a rising radio flux made it worth searching for a kilonova event. Read More ›

First light of ENGRAVE and a potential NS-BH merger 20 August 2019
A few months ago, the hunt for gravitational waves as part of the third observing run (O3) was initiated by the Advanced LIGO and Advanced Virgo gravitational-wave detectors on April 1, 2019. Both detectors have been upgraded since they were last in operation and have already reported more than 20 gravitational-wave candidate events of either merging binary black holes or merging binary neutron stars.

AT2017gfo Data Release 25 February 2019
ESO’s VLT + X-Shooter observed AT2017gfo nightly for 10 consecutive nights after discovery providing complete spectral coverage from 3300 Angstroms to 2.5 microns. The data were published in the papers Pian et al. 2017, Nature, 551, 67 and Smartt et al. 2017, Nature, 551, 75. The ENGRAVE collaboration have fully reduced all the data in a uniform manner (data reduced by J. Selsing) and spectrophotometrically calibrated to published photometry of AT2017gfo (by J. Gillanders). Read More ›

ENGRAVEr's mind under pressure - Dry run before Christmas 05 December 2018
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! Read More ›

ENGRAVE collaboration meeting 28 August 2018
The first ENGRAVE all-hands meeting was held on 31st October 2018 at the Max Planck Institute for Extraterrestrial Physics in Garching. Thanks to our hosts Ting-Wan Chen, Tassilo Schweyer, Jan Bolmer for organising and Prof Kirpal Nandra for his generous support of the meeting. More details for participants are on our wiki Read More ›

ENGRAVE awarded VLT Large Programme 02 August 2018
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. Read More ›

ENGRAVE is formed 28 February 2018
The ENGRAVE (Electro-magnetic counterparts of gravitational waves at the Very Large Telescope) project was founded on 28th February 2018, with the establishment of the Governing Council and a set of founding principles. Read More ›
