Galaxy mergers are expected to produce multiple supermassive black holes ( SMBHs ) in close-separation , but the detection of such SMBHs has been difficult . 2MASS J165939.7 + 183436 is a red active galactic nucleus ( AGN ) that is a prospective merging SMBH candidate owing to its merging features in Hubble Space Telescope imaging and double-peaked broad emission lines ( BELs ) . Herein , we report a Gemini Multi-Object Spectrograph Integral Field Unit observation of a double-peaked broad H \alpha line of 2MASS J165939.7 + 183436 . Furthermore , we confirm the existence of two BEL peaks that are kinematically separated by 3000 km s ^ { -1 } , with the SMBH of each BEL component weighing at 10 ^ { 8.92 \pm 0.06 } M _ { \odot } and 10 ^ { 7.13 \pm 0.06 } M _ { \odot } , if they arise from independent BELs near the two SMBHs . The BEL components were not separated at > 0 \farcs 1 ; however , under several plausible assumptions regarding the fitting of each spaxel , the two components are found to be spatially separated at 0 \farcs 085 ( \sim 250 pc ) . Different assumptions for the fitting can lead to a null ( < 0 \farcs 05 ) or a larger spatial separation ( \sim 0 \farcs 15 ) . Given the uncertainty regarding the spatial separation , various models , such as the disk emitter and multiple SMBH models , are viable solutions to explain the double BEL components . These results will promote future research for finding more multiple SMBH systems in red AGNs , and higher-resolution imaging validates these different models .
