Resumo: In this talk, I will discuss one of the alternative theories to dark matter named MOdified Gravity (MOG) on the galactic scale.
I have investigated MOG theory and the dark matter model by testing their ability to describe the local dynamics of the Milky Way in vertical and transverse directions by using observation data such as the vertical dispersion, rotation curve, surface density, and number density of stars.
The results show that two models of MOG and CDM are able to describe equally well the rotation curve and the vertical dynamics of stars in the local MW.
