Page 4: Research news on Gravitational waves

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.

Pulsars could have tiny mountains

Imagine a star so dense that a teaspoon of its material would weigh as much as Mount Everest, spinning hundreds of times per second while beaming radio waves across the universe. These are pulsars, the collapsed cores of ...

The importance of gravitational waves

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was the first recorded event of gravitational waves. And it helped confirm Einstein's theory of general ...

Astrophysicist searches for gravitational waves in new way

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe's gravitational wave background—the constant flow of waves that churn through the cosmos, warping the very fabric ...
