Scientific paper

Observations of dynamics of galaxies and plasma in the universe led us to the conclusion that there exists a huge amount of matter that is invisible, the so called "dark matter". Rotation curves of galaxies represent important evidences for introducing this concept. In this article we present the data interpretation for the rotation curve of NGC6503, introducing a new density distribution function in order to describe the behaviour at large distances from the center of the galaxy. One of the result's possible implications is a change in the classical approach regarding the matter and its movement in galaxies, as an attempt to explain the rotation curves of galaxies.
