Galactic kinematics is a branch of astrophysics that focuses on studying the motions and dynamics of stars and other celestial objects within galaxies. By analyzing the velocities and trajectories of these objects, researchers can gain insights into the structure, evolution, and interactions of galaxies. This field often involves studying the rotation of galaxies, the distribution of mass within them, and the gravitational forces that influence the motion of stars and gas clouds. Galactic kinematics plays a crucial role in our understanding of the formation and evolution of galaxies and the universe as a whole.
