LIGO-Virgo Finds Mystery Object in "Mass Gap"
June 25, 2020
Large stars that die collapse into their gravity fields and become black holes, the lightest being five times the mass of our sun (solar mass). Smaller stars die in an supernova explosion whose remnants are called neutron stars, the heaviest of which is 2.5 solar masses. What lies between 2.5 and 5 solar masses? A mystery object has been detected by the the National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo detector in Europe. The 2.6 solar mass object was seen while it merged with a black hole of 23 solar masses on 14 August 2019. A paper about the detection has been accepted for publication in The Astrophysical Journal Letters.

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
