Gravity waves indicate the merger of a massive black hole and a much less massive companion that may represent a new class of objects.

News

New technique touted for spotting elusive black hole mergers

18 November 2019 Astronomy Now

Black holes merging in the accretion disc of a supermassive black hole like the one at the core of the Milky Way might generate a visible signature, astronomers say.

News

Black hole gobbles neutron star, belches gravity waves

19 August 2019 Astronomy Now

Gravity waves detected 14 August indicate the apparent destruction of a neutron star being ripped apart by a black hole, researchers say

News

Upgrades to gravity wave detectors promise more discoveries

3 April 2019 Astronomy Now

After major upgrades to improve sensitivity, the LIGO and Virgo gravitational wave observatories are set to begin a year of joint observations.
