"Dusty Winds in Active Galactic Nuclei: An Infrared Polarimetric Approach"
Magnetohydrodynamical theories consider the obscuring dusty environment of active galactic nuclei (AGN) to be part of an outflowing dusty wind moving away from the active nuclei. In this framework, the obscuring dusty environment is a particular region of an outflowing dusty wind, where dusty and optically thick clouds are formed. The dusty winds are strongly related to the accretion rate and magnetic field strength of the active nuclei, which play an important role in the creation, morphology and evolution of the obscuring dust. Through high-angular (~0.1"-0.4") infrared (IR, 1-13 micrometers) polarimetric observations, this talk presents new insights about (1) the evolution and dynamics of the dusty winds within the AGN unified scheme, and (2) the AGN-host galaxy interaction. Although several models have been made to account for the outflowing dusty winds, the magnetic fields at the position of this obscuring dusty structure remains poorly characterized. Through near-IR (1-5 micrometers) polarimetric observations using MMT-Pol at the 6.5-m MMT, the magnetic field strength and geometry, accretion and outflow mass rates within the clumpy torus of NGC 1068 were estimated. The AGN-host galaxy interaction by the jet of NGC 1068 and the dust composition in and around the AGN were able to be investigated using mid-IR (7.5-13 micrometers) imaging- and spectroscopic polarimetric observations by CanariCam on the 10.4-m Gran Telescopio CANARIAS (GTC). Based on these results, this talk will present the potential of polarimetric techniques for the next generation of 30-m telescopes.
