• Meet GW190521-a black hole merger for the record books

    16 days ago - By Ars Technica

    Numerical simulation of two black holes that inspiral and merge, emitting gravitational waves. The black holes have large and nearly equal masses, with one only 3% more massive than the other.
    The LIGO/VIRGO collaboration has picked up a gravitational wave signal from another black hole merger-and it's one for the record books.
    The merger is the most massive and most distant yet detected by the collaboration, its signal traveling across the universe for a billion years before reaching Earth. The merger also produced the most energetic signal detected thus far, showing up in the data as...
