Page 6: 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.
Space itself may have created galaxies
According to new research, the earliest seeds of structures may have been laid down by gravitational waves sloshing around in the infant universe.

Gravitational waves could give us insights into fast radio bursts
Fast radio bursts (FRBs) are mysterious pulses of energy that can last from a fraction of a millisecond to about three seconds. Most of them come from outside the galaxy, although one has been detected coming from a source ...

Gravitational waves may prove black holes' quantum effect and resolve the dark matter problem
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 ...
A CubeSat mission will detect X-rays from GRBs and black-hole mergers
The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now to tie signals across multiple domains—for example, a gravitational wave and the associated electromagnetic ...

Quantum correlations could solve the black hole information paradox
The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a subtle signature in gravitational ...

Latest gravitational wave observations conflict with expectations from stellar models
Almost 300 binary mergers have been detected so far, indicated by their passing gravitational waves. These measurements from the world's gravitational wave observatories put constraints on the masses and spins of the merging ...
Black hole genealogy: A new way to discover 'ancestors' of cosmic phenomena
A research team has proposed a new method to reconstruct the "family tree" of black holes. Published in The Astrophysical Journal, this research offers a way to infer the properties of the black hole progenitors of these ...

Detecting the gravitational wave memory effect from core-collapse supernovae
Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing gravitational wave will ...
