THE NET RADIAL FLOW VELOCITY OF THE NEUTRAL HYDROGENIN THE OVAL DISTORTION OF NGC 4736
ABSTRACT: The net radial flow velocity of gas is an important parameter for understanding galaxy evolution. It is difficult to measure in the presence of the elliptical orbits of an oval distortion because the mathematical model describing the observed velocity is degenerate in the unknown velocity components.
