Let’s get (gravitationally} loud

In September 2015, gravitational waves (GWs) were detected for the first time by LIGO (Laser Interferometer Gravitational Observatory). Gravitational waves are ripples in spacetime produced by the acceleration of massive objects. To read more about this monumental discovery and gravitational wave astronomy in general, see this astrobite. This first signal was generated in the final fraction of a second before two black holes merged into a single object. Neutron star mergers are also likely candidates for gravitational wave production and the authors of this paper are particularly interested in the emission of gravitational waves after the neutron stars have merged — they demonstrate that the first 10 ms of this post-merger phase is the most GW-“luminous” period of the neutron star binary evolution. … (Astrobites)
