In 2015 the LIGO detectors observed, for the first time, a gravitational wave passing
through the Earth produced by the collision of two black holes. Such an event was a
milestone for astrophysics and it provided a remarkable confirmation of the general
theory of relativity. Since then, as many as ninety gravitational waves have
been observed by the LIGO and Virgo experiments, including signals from binary
neutron stars and neutron- star - black-hole binaries. These observations rely on
precise theoretical predictions of the two-body dynamics and
gravitational radiation. After reviewing the synergetic approach that successfully
combines analytical and numerical relativity to produce highly accurate waveform
models, I will discuss the most compelling and challenging findings from the most
recent LIGO- Virgo observing run regarding astrophysics, gravity and fundamental
physics.
