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...

How black holes turn cusps into cores (2002)
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...
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...
