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.
When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits ...

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

Black holes are some of the most mysterious objects in the universe, but they aren't always silent. When two black holes are close enough to each other, they spiral toward one another, eventually crashing in an enormous explosion ...

Scientists have detected the "fingerprints" of a black hole's event horizon—the boundary from which nothing can escape—for the first time, according to research published Wednesday.

If, in space, no one can hear you scream, it seems that you can actually hear the sound of a crash when two black holes collide. Using the loudest gravitational wave ever heard, two Australian scientists and colleagues have ...

Picture the Milky Way not as a silent pinwheel of stars but as something that quietly sings. Scattered through it are millions of pairs of dead stars, mostly white dwarfs, whirling around each other and stirring ripples in ...

Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in astronomy. Today, we have a thorough understanding of signals that travel far from their sources through ...

Galactic collisions are events of breathtaking proportions. The supermassive black holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, ...

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...
The physics of neutron stars are almost too fantastic to believe: something the weight of two suns compacted to a sphere the size of a city. Each teaspoon of its material would weigh billions of tons. If you've done any reading ...
