Core Formation by a Population of Massive Remnants
David Merritt, Slawomir Piatek, Simon Portegies Zwart +1
Core radii of globular clusters in the Large and Small Magellanic Clouds show an increasing trend with age. We propose that this trend is a dynamical effect resulting from the accu…
How black holes turn cusps into cores
Marc Hemsendorf
Collapsing collisionless particle systems form gravitational bound halos with cuspy density profiles. Also hierarchical merging of these systems produce remnants with cuspy central…
Instability of the Gravitational N-Body Problem in the Large-N Limit
Marc Hemsendorf, David Merritt
We use a systolic N-body algorithm to evaluate the linear stability of the gravitational N-body problem for N up to 1.3 x 10^5, two orders of magnitude greater than in previous exp…
Systolic and Hyper-Systolic Algorithms for the Gravitational N-Body Problem, with an Application to Brownian Motion
E. N. Dorband, Marc Hemsendorf, David Merritt
A systolic algorithm rhythmically computes and passes data through a network of processors. We investigate the performance of systolic algorithms for implementing the gravitational…
Collisional dynamics around binary black holes in galactic centers
Marc Hemsendorf, Steinn Sigurdsson, Rainer Spurzem
We follow the sinking of two massive black holes in a spherical stellar system where the black holes become bound under the influence of dynamical friction. Once bound, the binary…
