Description
The nature of the luminous IR sources in galaxy nuclei
has long been under debate. The large columns of dust
often obscuring the inner regions
of active galaxies make it necessary to use long wave
diagnostic tools such as submm and radio emission. In
extreme cases, emission from the nucleus is optically thick
even at FIR wavelengths.
Submm- and mm astrochemistry is emerging as a promising new
tool to explore the impact of the obscured nuclear activity on its
surrounding ISM - and hence enable us to gather information
on its nature and evolutionary stage.
