Gravitational waves from a binary black hole merger observed by LIGO and Virgo

27 September 2017 Astronomy Now

The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave signal recorded by the Virgo detector, and highlights the scientific potential of a three-detector network of gravitational-wave detectors.

Seeds of supermassive black holes could be revealed by gravitational waves

27 June 2016 Astronomy Now

Gravitational waves captured by space-based detectors could help identify the origins of supermassive black holes, according to new computer simulations. Durham University’s Institute for Computational Cosmology ran the huge cosmological simulations that can be used to predict the rate at which gravitational waves caused by collisions between the monster black holes might be detected.
