We propose to image three optically selected kpc-scale triple-AGN candidates with Chandra, HST, and EVLA. The detection of three luminous hard X-ray point sources in each system would confirm their triple AGN nature unambiguously, enabling the first direct evidence for galaxies containing triple massive black holes. The joint HST and EVLA imaging will help characterize the excitation mechanism of the observed emission (AGN, starburst, and/or shocks), and will explore host galaxy morphologies and spatially resolved star formation activity in these unique mergers. WFC3 (F336W and F105W) imaging of optically selected kpc-scale triple AGN candidates. F105W imaging for host galaxy morphology. F336W imaging for small-scale star formation. 12 false false 0.0 0.0 false false false SUPPORTED GALAXY INTERACTING GALAXY MULTIPLE NUCLEI SEYFERT J2000 J2000 sdss r 15.90 GALAXY INTERACTING GALAXY MULTIPLE NUCLEI SEYFERT J2000 J2000 sdss r 15.70 GALAXY INTERACTING GALAXY MULTIPLE NUCLEI SEYFERT J2000 J2000 sdss r 15.18 WFC3/IR Imaging No No F105W WFC3/UVIS Imaging No No F336W WFC3/IR Imaging No No F105W WFC3/UVIS Imaging No No F336W WFC3/IR Imaging No No F105W WFC3/UVIS Imaging No No F336W POS-TARG DITHER 0.572 LINE 0.365 false false 74.653 4 18.528 WFC3-IR-DITHER-BOX-MIN 1 false POS-TARG DITHER 0.135 LINE false false 3 46.84 WFC3-UVIS-DITHER-LINE-3PT 2 false The scheduling data was generated by CASM 21.0.
