• TITLE: How the Non-Axisymmetric Shape of the Milky Way Could Explain the Rotation Curve Flatness without Dark Matter

  ABSTRACT: Instead of considering our Galaxy as a disc with a density directly dependent on the distance from the center of the Galaxy, the objective of this study is to propose a new method that will rely on a N-body simulation and a non-axisymmetric and fully baryonic mass model of our Galaxy. There are a lot of existing N-body simulations of our Galaxy about kinematics, as, for example, [1]. This is the first N-body simulation that allows to retrieve the rotation curves of the Milky Way, to retrieve the rotational speeds with a static model. This approach allows us to see the contribution of each arm to the rest of the Galaxy and to understand the flatness of the rotational curves between 10 and 15 kpc from the center of our Galaxy: the inner arm helps to accelerate the rotational motion, as the outer arm will decelerate it, but always lower than the acceleration brought by the inner arm.
