A New Hybrid Technique for Modeling Dense Star Clusters
Carl L. Rodriguez, Bharath Pattabiraman, Sourav Chatterjee +4
The "gravitational million-body problem," to model the dynamical evolution of a self-gravitating, collisional N-body system with ~10^6 particles over many relaxation times, remains…
Black hole mergers and blue stragglers from hierarchical triples formed in globular clusters
Fabio Antonini, Sourav Chatterjee, Carl L. Rodriguez +4
Hierarchical triple-star systems are expected to form frequently via close binary-binary encounters in the dense cores of globular clusters. In a sufficiently inclined triple, grav…
Binary Black Hole Mergers from Globular Clusters: Implications for Advanced LIGO
Carl L. Rodriguez, Meagan Morscher, Bharath Pattabiraman +3
The predicted rate of binary black hole mergers from galactic fields can vary over several orders of magnitude and is extremely sensitive to the assumptions of stellar evolution. B…
Fast Algorithms for the Maximum Clique Problem on Massive Graphs with Applications to Overlapping Community Detection
Bharath Pattabiraman, Md. Mostofa Ali Patwary, Assefaw H. Gebremedhin +2
The maximum clique problem is a well known NP-Hard problem with applications in data mining, network analysis, information retrieval and many other areas related to the World Wide…
The Dynamical Evolution of Stellar Black Holes in Globular Clusters
Meagan Morscher, Bharath Pattabiraman, Carl Rodriguez +2
Our current understanding of the stellar initial mass function and massive star evolution suggests that young globular clusters may have formed hundreds to thousands of stellar-mas…
Fast Algorithms for the Maximum Clique Problem on Massive Sparse Graphs
Bharath Pattabiraman, Md. Mostofa Ali Patwary, Assefaw H. Gebremedhin +2
The maximum clique problem is a well known NP-Hard problem with applications in data mining, network analysis, informatics, and many other areas. Although there exist several algor…
A Parallel Monte Carlo Code for Simulating Collisional N-body Systems
Bharath Pattabiraman, Stefan Umbreit, Wei-Keng Liao +4
We present a new parallel code for computing the dynamical evolution of collisional N-body systems with up to N~10^7 particles. Our code is based on the the Henon Monte Carlo metho…
