A research group led by Kyoko Onishi at the SOKENDAI (The Graduate University for Advanced Studies) observed the barred spiral galaxy NGC 1097 with ALMA and found that the central supermassive black hole (SMBH) has a mass 140 million times the mass of the Sun.
This is video of new ALMA result on weighing supermassive black hole in the barred spiral galaxy NGC 1097.
