/ Abstract

Context. The central engines of many active galactic nuclei (AGNs) molecular and dusty disk, traced by submillimetre continuum and line emission. The latter is responsible for the bulk of the obscuration of the nucleus. These ﬁndings support the most recent radiative transfer calculations of the obscuring structures in AGNs, which ﬁnd a similar two-component structure.
