Reexamination of the CO Absorption Line in the M87 Nucleus

We analyzed the archival Atacama Large Millimeter/submillimeter Array data of the nuclear region of M87 and evaluated the molecular gas content from the CO(2–1) absorption line. We found an enigmatic variability in the absorption line depth between two epochs separated by only two months. We reexami...
