- GW190521 is the first clear detection of an intermediate-mass black hole made by any instrument. These types of sources produce their strongest gravitational waves in the low-frequency band (below 70 Hz). Martynov analysed the sensitivity of the LIGO detectors in the relevant band and helped improve laser and technical noise sources such as that from the auxiliary LIGO cavities. He has also successfully stabilised the angular motion of the LIGO Livingston test masses to keep the LIGO optical gain constant and minimise non-Gaussianity of data below 100 Hz.
