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 using Carmelian theory may be 10 to 100 times less than that calculated from standard Newtonian

When comparing the results from both proper-motion and radial velocity surveys in L1688, there is a trend for the 1D dispersions to be higher for samples of Class I/ﬂat-spectrum YSOs that reside in the cloud core compared to Class II/III dominated samples, which are located in the The radial velocity dispersion shows an almost constant value of 120 km s −1 out to 30 kpc and then continuously declines down to 50 km s −1 at about 120 kpc. This fall-off puts important constraints on the density profile and total mass of the dark matter halo of the Milky Way.

To check the plausibility of this possibility we (i) compared the preferred model to a model based on a 2-D inversion, where the number of Rayleigh paths has been reduced to match the coverage of the Love wave, (ii) inverted the Love dispersion curve, using the SV model as starting point, and vice versa inverted the Rayleigh dispersion using the SH model as starting point and (iii) considered the variation of RA based on bootstrap resampling of earthquake dispersion records. 2001-11-12 · A detailed discussion is given of the problems of providing for the instrumental profile in measuring the velocity dispersion. Using the existing version of the spectrograph, one can measure radial velocities and the dispersion of velocities to an accuracy of 5-10 km/s and 10-15 km/s, respectively. 2007-07-19 · 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 1987-01-01 2021-02-21 The dispersion completely characterizes the radial velocity distribution function if it is Gaussian: (2.5) Here, p ( v r ) dv r is the probability that an individual cluster galaxy has a radial velocity in the range v r to v r + dv r . We can use the velocity dispersion of a cluster to estimate its mass via the virial theorem.

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.

We use the 21 cm line of neutral atomic hydrogen (H i) to study H i velocity dispersion ({σ }{{H} {{I}}}) and H i phases as a function of galaxy morphology in 22 galaxies from The H i Nearby Galaxy Survey. generated models by computing synthetic group velocity dispersion curves for Rayleigh and Love wave fundamental modes and by comparing them with observations.

It has long been recognized that the radial velocity changes change the dispersion characteristics of dipole acoustic waves propagating along borehole. Methodologies have also been developed to identify the radial alteration from the dipole wave dispersion characteristics (e.g., Tang, 1996) and to determine the radial velocity profile (Burridge and Sinha, 1996).

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 second value is usually called the velocity dispersion, and denoted by the symbol sigma (σ).

To introduce radial anisotropy we consider shear‐wave speeds when calculating dispersion curves for Rayleigh and Love waves.
