LIGO Announces GW170104

The LIGO Scientific Collaboration announced the discovery of "GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2". "We've only heard the opening notes first but now we are starting to recognize the symphony of black-holes." said Columbia University Astrophysicist, Imre Bartos when describing the importance of the discovery of the third gravitational wave observed by humanity.

The Columbia Experimental Gravity Group is a longtime member of the LIGO Scientific Collaboration and had critical role in a broad range of field from instrumentation to astrophysics.
