In Sec. 2.2 we introduce several mass models for the dark halo of our Galaxy and derive how the line of sight velocity dispersion depends on the model parameters. In Sec. 2.3 we compare the data to the models and derive the best fit values of the parameters using χ2 fitting. Finally we discuss our Radial velocity dispersion in spheroidal and elliptical galaxies, as a function of radial distance from the center of the galaxy, has been derived from Cosmological Special Relativity. For velocity dispersions in the outer regions of spherical galaxies, the dynamical mass calculated for a galaxy Radial velocity is found by measuring the Doppler width of spectral lines of a collection of objects; the more radial velocities one measures, the more accurately one knows their dispersion. A central velocity dispersion refers to the σ of the interior regions of an extended object, such as a galaxy or cluster. 4 Radial velocity dispersion Assuming an spherically isotropic dynamic cloud of gases and stars, where the radial velocity dispersion is equal to the θ or φ dispersion (i.e.

radial flow problem exists within a finite domain, we use the Riemann–Liouville (with the corresponding Gr¨unwald for-mulation) fractional derivative [Oldham and Spanier, 1974; Miller and Ross, 1993]. The fractional termdirectly models anomalous dispersion due to extreme velocity … Figure 2.

σr2 = σθ,φ 2 ) the hydrostatic Jeans equation becomes d dΦ (ρ(r)σr2 ) = −ρ(r) . The radial velocity dispersion can be approximated as a function of the potential by = a (/ out) (out -), where out is the outer potential of the halo. For the parameters a and, we find that a = 0.29 ± 0.04 and = 0.41 ± 0.03. Because of their intrinsic emission-line diversity, CV stars are computed with their 3-component PCA eigenbasis plus a quadratic polynomial, over a radial velocity range of from -1000 to +1000 km/s. The velocity dispersion at a given Galactocentric radius r is estimated as the rms velocity averaged over all solid angles: σ2 GSR = ⟨a2 r⟩σ2 r + ⟨a2 θ⟩σ2 θ, (5) where ⟨.⟩ denotes the averaging over the sphere.
