We used the NVO facilities and tools to identify (relatively) isolated merging pairs of galaxies covering 125~sq~deg (2.5~deg \times 50~deg) from the 2MASS eXtended Source Catalog (XSC). We found 91 merging pairs in the 125~sq~deg region of the sky. Using the NVO tools and facilities (e.g., the NVO Registry, Open Sky Query, topcat, voplot), SkyView, and the SDSS SkyServer, we explored the physical properties and star formation and AGN activities of these 91 merging pairs over different wavelength regimes.

We present our results and the future plans for extracting a merging pairs catalog based upon the 2MASS XSC which would be the first large, homogeneous, and truly all--sky catalog of such galaxy systems based upon modern detector technology.

This research has made use of data obtained from or software provided by the US National Virtual Observatory, which is sponsored by the National Science Foundation.
