- GW190425 is the second binary neutron star event detected by the gravitational-wave detectors; notable for having a total mass that exceeds that of any known galactic neutron star binary. During the commissioning break before the science run Martynov travelled to the LIGO Livingston site and helped increase the resonating laser power in the LIGO detectors by 25% and improve the signal extraction efficiency from LIGO 4-km arms by 10%. These activities lead to the increase of the LIGO reach by 15% that helped detect the distant GW190425 event and improve estimates of the neutron star merger rate.
