For the first time, researchers have simultaneously measured the gravitational waves and the light from two merging neutron stars. ‘Multi-messenger astronomy’, combining the observation of ...

The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...

Three merging galaxies host three active black holes, offering rare insight into galaxy and black hole growth.
