MAGICS I. The First Few Orbits Encode the Fate of Seed Massive Black Hole Pairs
Nianyi Chen, Diptajyoti Mukherjee, Tiziana Di Matteo +3
The elusive massive black hole (MBH) seeds stand to be revealed by the Laser Space Antenna Interferometer through mergers. As an aftermath of galaxy mergers, MBH coalescence is a v…
