Possible first hints of low-frequency gravitational waves permeating the cosmos

Vanderbilt astrophysicists, led by Assistant Professor of Physics and Astronomy Stephen Taylor, are part of a group of researchers that may have found the first hints of low-frequency gravitational waves from supermassive black holes merging in other galaxies. The data was gathered and analyzed within the North American Nanohertz Observatory for Gravitational Waves. The paper, “The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background,” was published in the December 2020 issue of The Astrophysical Journal Letters and discussed at a news briefing during the American Astronomical Society’s virtual meeting on Jan. 11. According to a National Science …
