Spheroidal and elliptical galaxy radial velocity dispersion determined from Cosmological General Relativity

, 2007
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.

The Velocity Dispersion Profile of Nine Open Clusters in the Solar Neighborhood

The Astrophysical Journal
We analyze the velocity dispersion profiles of nine open clusters in the solar neighborhood using kinematic data from Gaia DR 3, aiming to identify potential dynamical signatures of stellar-mass black holes through a comparison of theoretical and ...

Minimal Position-Velocity Uncertainty Wave Packets in Relativistic and Non-relativistic Quantum Mechanics

, 2009
We consider wave packets of free particles with a general energy-momentum dispersion relation $E(p)$. The spreading of the wave packet is determined by the velocity $v = \p_p E$. The position-velocity uncertainty relation $\Delta x \Delta v \geq {1/2} ||$

On the ability of the Generalized Continuum Transport Model to properly capture dispersion

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
The ability of the Generalized Continuum Transport model to describe dispersion is studied through the comparison of the breakthrough curves with an analytical solution of the linear advection-dispersion Equation.

Distant star clusters of the Milky Way in MOND

, 2011
We determine the mean velocity dispersion of six Galactic outer halo globular clusters, AM 1, Eridanus, Pal 3, Pal 4, Pal 15, and Arp 2 in the weak acceleration regime to test classical vs. modified Newtonian dynamics (MOND).

Velocity Dispersion Profiles in Dark Matter Halos

The Astrophysical Journal, 2004
Numerous numerical studies indicate that dark matter halos show an almost universal radial density profile. The origin of the profile is still under debate. We investigate this topic and pay particular attention to the velocity dispersion profile. To this end we have performed high-resolution simulations with two independent codes, ART and {\sc Gadget}.

CIRCULAR VELOCITY AND CENTRAL VELOCITY DISPERSION IN LOW SURFACE BRIGHTNESS GALAXIES [PDF]

, 2007
We analyzed a sample of high and low surface brightness (HSB and LSB) disc galaxies and elliptical galaxies to investigate the correlation between the circular velocity (V_c) and the central velocity dispersion (sigma_c). We better defined the previous V_c-sigma_c correlation for HSB and elliptical galaxies, especially at the lower end of the sigma_c ...
