Gravitational waves as a research area encompass the theoretical modeling, detection, and astrophysical interpretation of ripples in spacetime predicted by general relativity and alternative gravity theories. This field integrates general relativity, numerical relativity, data analysis, and experimental physics to study compact object mergers, core-collapse supernovae, cosmological backgrounds, and potential beyond–standard-model phenomena. Research focuses on waveform modeling, parameter estimation, tests of gravity in the strong-field regime, and multi-messenger astronomy combining electromagnetic and neutrino signals. It also drives the development and operation of ground- and space-based interferometric observatories, pulsar timing arrays, and analysis pipelines for weak, transient, and stochastic signals.
Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These signals correspond to minutes ...

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by LIGO in 2015. These black ...
