Issue Date: | 2016 | Journal: | THE ASTROPHYSICAL JOURNAL LETTERS | Number: | 829 | Issue: | 1 | First Page: | L7 | Abstract: | We have detected in ALMA observations CO J=6\to 5 emission from the nucleus of the Seyfert galaxy NGC 1068. The low-velocity (up to ±70 km s<SUP>-1</SUP> relative to systemic) CO emission resolves into a 12 × 7 pc structure, roughly aligned with the nuclear radio source. Higher-velocity emission (up to ±400 km s<SUP>-1</SUP>) is consistent with a bipolar outflow in a direction nearly perpendicular (≃80°) to the nuclear disk. The position-velocity diagram shows that in addition to the outflow, the velocity field may also contain rotation about the disk axis. These observations provide compelling evidence in support of the disk-wind scenario for the active galactic nucleus obscuring torus. | URI: | http://hdl.handle.net/20.500.12386/30704 | URL: | https://iopscience.iop.org/article/10.3847/2041-8205/829/1/L7 | ISSN: | 2041-8205 | DOI: | 10.3847/2041-8205/829/1/L7 | Bibcode ADS: | 2016ApJ...829L...7G | Fulltext: | open |
