Relaxation Processes and Black Holes in Star Clusters andGalactic Nuclei (2009)

Marc Hemsendorf, Emil Khalisi, Chingis Omarov, Rainer Spurzem

We use high-precision direct N-body integration to study questions of the thermodynamic be-haviour of dense stellar systems and of the state of dense stellar systems interacting with binary black...

Core Formation by a Population of Massive Remnants (2004)

Merritt, David, Piatek, Slawomir, Zwart, Simon Portegies, Hemsendorf, Marc

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 accumulation of massive...

Instability of the gravitational N-body problem in the large-N limit (2002)

Merritt, David, Hemsendorf, Marc

Also archived in: arXiv:astro-ph/0205538 v3 18 Jul 2002 AND Rutgers Astrophysics Preprint Series No. 336

Instability of the gravitational N-body problem in the large-N limit (2002)

How black holes turn cusps into cores (2002)

Hemsendorf, Marc

Collapsing collisionless particle systems form gravitational bound halos with cuspy density profiles. Also hierarchical merging of these systems produce remnants with cuspy central density profiles....

Instability of the Gravitational N-Body Problem in the Large-N Limit (2002)

Hemsendorf, Marc, Merritt, David

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 experiments. For the...

Systolic and Hyper-Systolic Algorithms for the Gravitational N-Body Problem, with an Application to Brownian Motion (2001)

Dorband, E. N., Hemsendorf, Marc, Merritt, David

A systolic algorithm rhythmically computes and passes data through a network of processors. We investigate the performance of systolic algorithms for implementing the gravitational N-body problem on...

Collisional dynamics around binary black holes in galactic centers (2001)

Hemsendorf, Marc, Sigurdsson, Steinn, Spurzem, Rainer

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 hardens by...

Systolic and Hyper-Systolic Algorithms for the Gravitational N-Body Problem, with an Application to Brownian Motion (2001)

Ernst Nils Dorb, 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 N-body problem on...

Three poster contributions to the Rutgers Dynamics Conference (1998)

1- Simulations of star clusters and galactic nuclei: rotation and other challenges (R. Spurzem & C. Einsel) 2- Relaxation of elliptical galaxies (C. Boily) 3- Simulations with an Hybrid Nbody-Scf...
