From comparison of the behavior of the circular velocities of the clouds in the central regions of the Galaxy with the results of numerical simulation of the rotation curve the value R= 8.2 + or - /sup 0.9//sub 0.7/ kpc is obtained. Rotation curves for the Galaxy for two galactocentric ...

Galaxy rotation curves from General Relativity with Renormalization Group corrections We consider the application of quantum corrections computed using renormalization group arguments in the astrophysical domain and show that, for the most n...

Galaxy rotation curves: the effect of [(j)vec] ×[(B)vec]vec{j} timesvec{B} force Using the Galaxy as an example, we study the effect of [(j)vec] ×[(B)vec]vec{j} times vec{B} force on the rotational curves of gas and plasma in galaxies. Acceptable model for the galactic ...
The flat rotation curves are counter to what we see for the distribution of stars and gas in the spiral galaxies. The surface luminosity of the disk falls off exponentially with radius, implying that the mass of luminous matter, mostly stars, is concentrated around the galactic center. The ...
We present new long-slit H伪 spectroscopy for 403 non-interacting spiral galaxies, obtained at the Palomar Observatory 5 m Hale telescope, which is used to derive well-sampled optical rotation curves. Because many of the galaxies show op... B Catinella,MP Haynes,R Giovanelli 被引量: 34发表...
Galaxy Rotation Curves TheLCDM cosmology iswidely regarded by the scientific community nowadays as the leading model for the universe. Specifically, in order to explain thediscrepancy in galaxy rotation curves,it assumes the existence ofdark matter halosaround each and every galaxy. However,various rec...
Galaxy rotation curve for the Milky Way. Vertical axis is speed of rotation about the Galactic Center. Horizontal axis is distance from the Galactic Center in kpcs. The Sun is marked with a yellow ball. The observed curve of speed of rotation is blue. The predicted curve based upon stellar...
Using the multiplicity of solutions for the projectable case of the covariant extension of Ho?ava-Lifshitz gravity, we show that an appropriate choice for the auxiliary field allows for an effective description of galaxy rotation curves. This description is based on static and spherically symmetric ...
A modification of Newtonian gravitational attraction which arises in the context of modern attempts to unify gravity with the other forces in nature can produce rotation curves for spiral galaxies which are nearly flat from 10 to 100 kpc, bind clusters of galaxies, and close the universe with the...
