In an effort to further evaluate the evolution of X-ray properties along the sequence of merging galaxies, we have performed an analysis of the Toomre sequence of galaxies in the Chandra X-Ray Observatory archives. The merging sequence is ideal for investigating the role interactions and mergers play in the development and evolution of X-ray features.
Nine galaxies across the Toomre sequence were analyzed to determine whether the X-ray point sources could be used to further constrain the merger and interaction histories of more isolated galaxies. As the evolution histories of isolated galaxies are uncertain, the X-ray properties of the diffuse gas and point sources could serve as viable estimators of past mergers. A previous study of the Toomre sequence found that the X-ray luminosity peaks 300 Myr before nuclear coalescence. We are investigating if the X-ray point source population follows a similar trend. Variations in the temperature profiles of galaxies along the merging sequence will also be examined.
We have performed a similar study for Chandra archival compact groups. We will provide a comparison of properties observed in the Toomre merging galaxies and for the compact group galaxies. The results of both studies suggest that X-ray point sources can be used to evaluate the evolutionary state of a group.
