MAGICS III. Seeds sink swiftly: nuclear star clusters dramatically accelerate seed black hole mergers
Diptajyoti Mukherjee, Yihao Zhou, Nianyi Chen +2
Merger rate predictions of Massive Black Hole (MBH) seeds from large-scale cosmological simulations differ widely, with recent studies highlighting the challenge of low-mass MBH se…
MAGICS II. Seed black holes stripped of their surrounding stars do not sink
Yihao Zhou, Diptajyoti Mukherjee, Nianyi Chen +7
MBH seed mergers are expected to be among the loudest sources of gravitational waves detected by the Laser Interferometer Space Antenna (LISA), providing a unique window into the b…
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…
Fast Multipole Methods for -body Simulations of Collisional Star Systems
Diptajyoti Mukherjee, Qirong Zhu, Hy Trac +1
Direct -body simulations of star clusters are accurate but expensive, largely due to the numerous pairwise force calculations. To solve the post-million-body…
