X-ray and HST Imaging of Kpc-Scale Binary AGNs
Binary active galactic nuclei (AGN) with kiloparsec separations are of great value in understanding the role of galaxy mergers in AGN fueling and the interplay between supermassive black holes and their hosts. While pervasive in theoretical models, despite decades of searching, merging kpc-scale binary AGNs remain extremely difficult to find. Here we propose to observe four newly discovered, optically-selected kpc-scale binary Type 2 AGNs with Chandra and HST. The detection of two X-ray nuclei in each galaxy will confirm their binary AGN nature unambiguously, and triple the number of kpc-scale binary X-ray AGN known. The joint HST observations will explore host morphologies and small-scale star formation activity in these merging systems.
WFC3 (F336W and F105W) observations of kpc binary AGNs.
