A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals II
H Daisaka, N Nakasato, T Ishikawa +2
Evaluation of a wide variety of Feynman diagrams with multi-loop integrals and physical parameters and its comparison with high energy experiments are expected to investigate new p…
Global High-resolution -body Simulation of Planet Formation I. Planetesimal Driven Migration
Junko Kominami, Hiroshi Daisaka, Junichiro Makino +1
We investigated whether outward Planetesimal Driven Migration (PDM) takes place or not in simulations when the self gravity of planetesimals is included. We performed -body simu…
A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals
Shinji Motoki, Hiroshi Daisaka, Naohito Nakasato +5
Higher order corrections in perturbative quantum field theory are required for precise theoretical analysis to investigate new physics beyond the Standard Model. This indicates tha…
Origin of multiple nuclei in ultraluminous infrared galaxies
Hidenori Matsui, Takayuki R. Saitoh, Junichiro Makino +6
Ultraluminous infrared galaxies (ULIRGs) with multiple () nuclei are frequently observed. It has been suggested that these nuclei are produced by multiple major mergers of g…
Binary Formation in Planetesimal Disks I. Equal Mass Planetesimals
Junko K. Daisaka, Junichiro Makino, Hiroshi Daisaka
As to April 2010, 48 TNO (trans-Neptunian Object) binaries have been found. This is about 6% of known TNOs. However, in previous theoretical studies of planetary formation in the T…
Shock-induced star cluster formation in colliding galaxies
Takayuki R. Saitoh, Hiroshi Daisaka, Eiichiro Kokubo +5
We studied the formation process of star clusters using high-resolution N-body/smoothed particle hydrodynamcs simulations of colliding galaxies. The total number of particles is 1.…
Toward First-Principle Simulations of Galaxy Formation: II. Shock-Induced Starburst at a Collision Interface During the First Encounter of Interacting Galaxies
Takayuki R. Saitoh, Hiroshi Daisaka, Eiichiro Kokubo +5
We investigated the evolution of interacting disk galaxies using high-resolution -body/SPH simulations, taking into account the multiphase nature of the interstellar medium (ISM…
Toward first-principle simulations of galaxy formation: I. How should we choose star formation criteria in high-resolution simulations of disk galaxies?
Takayuki R. Saitoh, Hiroshi Daisaka, Eiichiro Kokubo +5
We performed 3-dimensional N-body/SPH simulations to study how mass resolution and other model parameters such as the star formation efficiency parameter, C* and the threshold dens…
Spatial Structure and Coherent Motion in Dense Planetary Rings Induced by Self-Gravitational Instability
H. Daisaka, S. Ida
We investigate the formation of spatial structure in dense, self-gravitating particle systems such as Saturn's B-ring through local -body simulations to clarify the intrinsic ph…
