アタカマ大型ミリ波サブミリ波干渉計
9Spitch was observed with the Atacama Large Millimeter Array (ALMA) 12-meter antennas in December 2017 as part of project 2017.1.00814.S. The data revealed the presence of atomic carbon and carbon monoxide as a tracer of star formation. It was estimated that the total star formation rate of the molecular ring is about . ALMA also detected the cyanide radical travelling twice the velocity of the rotation of the molecular ring, with a radial velocity of . This is explained as a possible interaction between material outflowing from the AGN and interstellar material.
