An interacting galaxy pair in the Bootes void

The first identified pair of interacting galaxies in the Bootes void is reported. The galaxies, CG 692 (IRAS 1519 + 5050) and CG 693, have redshifts 0.0572 and 0.0575, respectively, and a mutual separation of about 34 kpc. CG 692 is experiencing widespread star formation, at a rate estimated to be 1...

More Information
Summary:The first identified pair of interacting galaxies in the Bootes void is reported. The galaxies, CG 692 (IRAS 1519 + 5050) and CG 693, have redshifts 0.0572 and 0.0575, respectively, and a mutual separation of about 34 kpc. CG 692 is experiencing widespread star formation, at a rate estimated to be 18.4 solar masses/yr. CG 693 is a Seyfert 1, the third AGN found in the Bootes void, with a small amount of extranuclear star formation. The pair is another example of interacting galaxies displaying starburst and Seyfert activity apparently triggered by the interaction.
