Gravitational Physics

Although the gravitational wave signal emitted by the merging of compact objects, such as black holes or neutron stars, has almost become “normal”, we are [...]

Since 2015, the LIGO-Virgo-KAGRA collaboration has been detecting and analyzing gravitational-wave signals, with about 90 observations of compact binary coalescence signals after the third-observing runs. [...]

With increasing sensitivities of the current ground-based gravitational wave (GW) detectors, the prospects of detecting a gravitationally lensed GW signal are going to improve in [...]

The analytical modelling of gravitational waves in general relativity has been one of the key element to allow the numerous detections by the LIGO-Virgo-KAGRA collaboration. [...]

The detection of 90+ gravitational wave signals produced by coalescing black holes or neutron stars have opened up a rich discovery space for astrophysics, gravitation, [...]

In recent years there has been an increased interest in modelling the nonlinear dynamics in theories beyond general relativity. Recent work by different groups has [...]
