LIGO and Virgo team members estimate that the candidate gravitational signal referred to as S190426c originated from the region outlined on the sky map. The signal shows hints of originating from a merger between a black hole and neutron star. Both of the twin LIGO detectors, and Virgo, picked up the signal, narrowing its location to a region occupying about three percent of the total sky.
