Kinematics of the ionized gas around ultra-luminous X-ray sources in nearby spiral galaxies.
Abstract
We present scanning Fabry-Perot observations of the ionized gas surrounding ultra-luminous X-ray sources in four nearby spiral galaxies. We identify non-circular motions that may be associated with either isotropically or beamed expanding gas. Most of the sources observed show asymmetrical distribution of the ionized emission as well as asymmetrical distribution of gas motions. We also study the location of these sources in the context of the whole galaxy in different wavelengths. This work is part of an analysis to determine the nature of these sources and their correlation (if any) with the kinematics of host galaxy.
