AGN Triality of Triple Mergers: Multiwavelength Classifications

We present results from a multi-wavelength analysis searching for multiple AGN systems in nearby (z<0.077) triple galaxy mergers. Combining archival Chandra, SDSS, WISE, and VLA observations, we quantify the rate of AGN, as well investigate possible connections between SMBH accretion merger environments. Analyzing observations 7 mergers, find that 1 has single (NGC 3341); discover, first time, 4 likely dual (SDSS J1027+1749, SDSS J1631+2352, J1708+2153, J2356-1016); confirm one system, J0849+1114; our sample remains ambiguous J0858+1822). WISE data, trend increasing N_H (associated with primary AGN) function W1-W2 color, reflecting motions gas dust are coupled merging environments, where large amount both can be funneled into active central region during Additionally, system highest levels while candidates all have lower levels; these consistent theoretical simulations suggest higher nuclear more to activate
