English Abstract
Galaxies are one of the most important members of astronomical family.
They are consisting of the stars, clusters, and the effect of the power of gravity responsible of concatenate between them.
This power of gravity constituting various kinds of galaxies, and the most powerful of this gravity lies in the center of the galaxies.
In this present work, we suggest (24) formulas, to descript the distribution of mass density in the galaxy.
These formulas are based on some known formula used by other published works.
Four formula forms these formulas are tested by using them in the calculation of the mass density, total galactic mass, and the rotation curves, to see the shape of curves.
These suggested formulas are used in the calculation of the rotation curves of three galaxies: (NGC925, NGC5218, M101) Where, some of these formulas show good agreements with the observed data.
The best six formulas are chooses in the calculation of rotation curves of four galaxies: (NGC3877, NGC3972, NGC5585, NGC3917) Our result shows very good agreements with observed published data.
