The ecology of star clusters and intermediate mass black holes in the Galactic bulge
Simon Portegies Zwart, Holger Baumgardt, Stephen L. W. McMillan +3
We simulate the inner 100pc of the Milky-Way Galaxy to study the formation and evolution of the population of star clusters and intermediate mass black holes. For this study we per…
Three-Body Affairs in the Outer Solar System
Yoko Funato, Junichiro Makino, Piet Hut +2
Recent observations (Burnes2002,Veillet2002,Margot2002a) have revealed an unexpectedly high binary fraction among the Trans-Neptunian Objects (TNOs) that populate the Kuiper Belt.…
A New Time-Symmetric Block Time-Step Algorithm for N-Body Simulations
Murat Kaplan, Hasan Saygin, Piet Hut +1
Time-symmetric integration schemes share with symplectic schemes the property that their energy errors show a much better behavior than is the case for generic integration schemes.…
Performance Tuning of N-Body Codes on Modern Microprocessors: I. Direct Integration with a Hermite Scheme on x86_64 Architecture
Keigo Nitadori, Junichiro Makino, Piet Hut
The main performance bottleneck of gravitational N-body codes is the force calculation between two particles. We have succeeded in speeding up this pair-wise force calculation by f…
On Math, Matter and Mind
Piet Hut, Mark Alford, Max Tegmark
We discuss the nature of reality in the ontological context of Penrose's math-matter-mind triangle. The triangle suggests the circularity of the widespread view that math arises fr…
