Unexpected Formation Modes of the First Hard Binary in Core Collapse
Ataru Tanikawa, Piet Hut, Junichiro Makino
The conventional wisdom for the formation of the first hard binary in core collapse is that three-body interactions of single stars form many soft binaries, most of which are quick…
N-body simulation for self-gravitating collisional systems with a new SIMD instruction set extension to the x86 architecture, Advanced Vector eXtensions
Ataru Tanikawa, Kohji Yoshikawa, Takashi Okamoto +1
We present a high-performance N-body code for self-gravitating collisional systems accelerated with the aid of a new SIMD instruction set extension of the x86 architecture: Advance…
Successive Merger of Multiple Massive Black Holes in a Primordial Galaxy
Ataru Tanikawa, Masayuki Umemura
Using highly-accurate -body simulations, we explore the evolution of multiple massive black holes (hereafter, MBHs) in a primordial galaxy that is composed of stars and MBHs. Th…
