Eclipse Prediction and Orbit Improvement for Asteroids: Theory and Application to Near Earth Asteroids
P. Tricarico, N. C. Hearn, G. Lake +1
Asteroids can be eclipsed by other bodies in the Solar System, but no direct observation of an asteroid eclipse has been reported to date. We describe a statistical method to predi…
Formation of Proto-Globular Cluster Clouds by Thermal Instability
Hyesung Kang, George Lake, Dongsu Ryu
Many models of globular cluster formation assume the presence of cold dense clouds in early universe. Here we re-examine the Fall & Rees (1985) model for formation of proto-globula…
The fate of LSB galaxies in clusters and the origin of the diffuse intra-cluster light
Ben Moore, George Lake, Joachim Stadel +1
We follow the evolution of disk galaxies within a cluster that forms hierarchically in a standard cold dark matter N-body simulation. At a redshift z=0.5 we select several dark mat…
The Structure and Dynamics of Cold Dark Matter Halos
Ben Moore, Sebastiano Ghigna, Fabio Governato +3
We investigate the internal structure of cold dark matter halos using high resolution N-body simulations. As the mass and force resolution are increased, halo density profiles beco…
Smooth Particle Hydrodynamics: Models, Applications, and Enabling Technologies
Piet Hut, Lars Hernquist, George Lake +3
We present the results from a two-day study in which we discussed various implementations of Smooth Particle Hydrodynamics (SPH), one of the leading methods used across a variety o…
On the origin of early type galaxies and the evolution of the interaction rate in the field
F. Governato, Jeffrey P. Gardner, J. Stadel +2
Using cosmological N-body simulations of critical (SCDM) and open (Omega_0=0.3, OCDM) cold dark matter models we have identified dark matter halos which are associated with the pro…
