A 'tsunami' of gravitational waves

As reported by the ARC Centre of Excellence for Gravitational Wave Discover(OzGrav).

An international team of scientists, including Australian researchers from the ARC OzGrav have collaborated on a study released earlier this month, presenting the largest number of gravitational wave detections to date - 90 detections!

Gravitational waves are cosmic ripples in space and time that are caused by some of the most violent and energetic processes in the Universe, like supernovas, merging black holes and colliding neutron stars--city-size stellar objects with a mass about 1.4 times that of the Sun.

The newest gravitational wave detections come from the second part of the third observing run which lasted from November 2019 to March 2020. There were 35 new gravitational wave detections in this period: 32 detections were from pairs of merging black holes; 3 were likely to come from the collision of a neutron star and a black hole.
