The mystery of AT 2019osy


engrave news 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.

First light of ENGRAVE and a potential NS-BH merger


engrave news 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


engrave news 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).

ENGRAVEr's mind under pressure - Dry run before Christmas


engrave news 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!
