In September 2015, the detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected, for the first time, gravitational waves generated by the merger of two black holes. To date, the detectors of the LVK collaboration—which unites LIGO (USA), the European Virgo, and Japan’s KAGRA—have detected gravitational wave signals from the mergers of black holes and... -

Laser GW antenna is the unique displacement meter, measuring distance 4 km between 40-kg masses with unique sensitivity about 10^{-19} m. Current sensitivity is close to Standard Quantum Limit (SQL), which is a consequence of Heisenberg uncertainty principle. We discuss the reasons of SQL (measurement noise and back action) and methods to surpass it: quantum non-demolition... -

Gravitational-wave astronomy offers new opportunities for probing fundamental physics. I will briefly review current and future detection techniques and the frequency ranges and observables they can access. I will then discuss two recent proposals that aim to extend the capabilities of gravitational-wave detection in complementary directions. First, I will present QuGrav, a... -

Gravitational waves (GWs) are independent of any particular theory of gravity. The universality of this notion is highlighted by the Raychaudhuri equation which is independent of any theory of gravity. This equation contains the Ricci tensor R as a key ingredient, thereby connecting spacetime geometry with matter-energy content. Under small metric perturbations, R is...
