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.
A study published in Nature has established a new benchmark in modeling the universe's most extreme events: the collisions of black holes and neutron stars. This research, led by Professor Jan Plefka at Humboldt University ...

There is a supermassive black hole at the center of our galaxy, and it's not alone. There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually ...

A study published in Physical Review Letters outlines a new approach for extracting information from binary systems by looking at the entire posterior distribution instead of making decisions based on individual parameters.
Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying waves propagating through ...
Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To observe them, ultra-precise ...
