Meet the Parents: The Progenitor Binary for the Supermassive Black Hole Candidate in E1821+643
The remnants of binary black hole mergers can be given recoil kick velocities up to 5000 km s ^−1 due to anisotropic emission of gravitational waves. E1821+643 is a recoiling supermassive black hole candidate with spectroscopically offset, broad emission lines, consistent with motion of the black ho...
