Internal Kinematics of Luminous Compact Blue Galaxies
Abstract
We describe the dynamical properties which may be inferred from HST/STIS spectroscopic observations of luminous compact blue galaxies (LCBGs) between 0.1 < z < 0.7. While the sample is homogeneous in blue rest-frame color, small size and line width, and high surface brightness, their detailed morphology is eclectic. Here, we determine the amplitude of rotation versus random, or disturbed motions of the ionized gas. This information affirms the accuracy of dynamical mass and M/L estimates from Keck integrated line widths, and hence also the predictions of the photometric fading of these unusual galaxies. The resolved kinematics indicates this small subset of LCBGs are dynamically hot, and unlikely to be embedded in disk systems.
