On 14 September, 2015, the two detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) in the US recorded the first direct detection of gravitational waves. This paper reviews the contributions to this discovery by V.B. Braginsky's group at the Physics Department of Lomonosov Moscow State University.
