Dark Matter Halos: The Dynamical Basis of Effective Empirical Models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We investigate the dynamical basis of the classic empirical models (specifically, Sersic-Einasto and generalized NFW) that are widely used to describe the distributions of collisionless matter in gala...
ZERNIKE BASIS TO CARTESIAN TRANSFORMATIONS
Instrumentation: adaptive optics Methods: analytical
2010/10/29
The radial polynomials of the 2D (circular) and 3D (spherical) Zernike functions are tabulated as powers of the radial distance. The reciprocal tabulation of powers of the radial distance in series of...
GALACTIC SUBSYSTEMS ON THE BASIS OF CUMULATIVE DISTRIBUTION OF SPACE VELOCITIES
Galaxy kinematics and dynamics-structure-solar neighbourhood
2009/1/15
A sample containing 4 614 stars with available space velocities and
high-quality kinematical data from the Arihip Catalogue is formed. For the purpose
of distinguishing galactic subsystems the cumul...
