Title: The Dust and Molecular Gas in the Torus of NGC 1068
Abstract:
In the context of the AGN unification paradigm, the concept of the
“torus” plays a crucial role to discern between Type-1 and Type-2 AGNs.
NGC 1068, a well-studied AGN across the electromagnetic spectrum, is a
nearby barred galaxy (d=14.4 Mpc) considered the prototypical Seyfert 2.
Using MATISSE at the VLTI, we have obtained direct evidence of the dusty
torus enshrouding the AGN in NGC 1068. The multi-band capabilities of
the instrument and the high spatial resolution that the interferometric
technique can achieve have enable us to study in detail the
characteristics of the obscuring dust and its spatial distribution. My
presentation will delve into these findings and discuss our latest
research on the molecular counterpart of the dusty torus. Using ALMA we
are able to resolve structures with a comparable angular resolution. The
revealed kinematics from the ALMA data suggest an ongoing merger event,
potentially contributing to the observed asymmetries in the torus and
the water maser disk.
