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.
Researchers from the University of Glasgow's Institute for Gravitational Research are celebrating the publication of a vast new treasure trove of gravitational wave detections, hailed as a milestone marking the coming of ...

A team of U.S. astronomers has observed a binary pair of white dwarfs where one star is actively devouring material from the other. Led by Emma Chickles at MIT, the researchers revealed one of the clearest views yet of how ...
Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most dramatic events. When black holes merge, the collision produces a new, larger black hole that ...

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of ...

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their ...
Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to accumulate their enormous masses, they must merge with each other. A research team led by Silke Britzen ...
