Realistic triaxial density--potential--force profiles for stellar systems and dark matter halos
Balsa Terzic, Benjamin J. Sprague
Popular models for describing the luminosity-density profiles of dynamically hot stellar systems (e.g., Jaffe, Hernquist, Dehnen) were constructed to match the deprojected form of…
Empirical Models for Dark Matter Halos. III. The Kormendy relation and the log(rho_e)-log(R_e) relation
Alister W. Graham, David Merritt, Ben Moore +2
We have recently shown that the 3-parameter density-profile model from Prugniel & Simien provides a better fit to simulated, galaxy- and cluster-sized, dark matter halos than an NF…
Empirical Models for Dark Matter Halos. II. Inner profile slopes, dynamical profiles, and rho/sigma^3
Alister W. Graham, David Merritt, Ben Moore +2
We have recently shown that both the Prugniel-Simien model and Sersic's function (hereafter referred to as the Einasto model when applied to internal density profiles) describe sim…
Empirical models for Dark Matter Halos. I. Nonparametric Construction of Density Profiles and Comparison with Parametric Models
David Merritt, Alister W. Graham, Ben Moore +2
We use techniques from nonparametric function estimation theory to extract the density profiles, and their derivatives, from a set of N-body dark matter halos. We consider halos ge…
Density-potential pairs for spherical stellar systems with Sersic light-profiles and (optional) power-law cores
Balsa Terzic, Alister W. Graham
Popular models for describing the luminosity-density profiles of dynamically hot stellar systems (e.g., Jaffe, Hernquist, Dehnen) were constructed with the desire to match the depr…
Noise-Induced Phase Space Transport in Time-Periodic Hamiltonian Systems
Balsa Terzic, Henry E. Kandrup
Orbits in a three-dimensional potential subjected to periodic driving, V(x^i,t)=[1+m_0 sin(omega t) V_0(x^i), divide naturally into two types, regular and chaotic, between which tr…
