Rotation of stars and gas in M 82.
Abstract
New observations of near IR emission and absorption lines along M 82's major axis yield radial velocity-position curves that differ markedly from those derived from lines at visible wavelengths. For the central disk we find identical rotation for the gas and the stars, contrary to earlier results. The rotation derived from emission and absorption lines at visible wavelengths refer to outer regions of the galaxy since at these wavelengths the central disk is obscured by dust.
