Title: Resolving the innermost dusty accretion in the brightest Type 1 AGN with the CHARA array
Abstract:
We believe that we have finally started to spatially resolve and
quantify the innermost dusty structure in AGN tori with long-baseline
interferometry in the infrared. A major goal here is to see if the
inner radial distribution of the accreting material is closely related
to the mode of the central engine: based on the results so far, this
might indeed be the case. However, our previous and on-going
observations have a big limitation in the baseline length, with which we
can only marginally resolve the structure, leaving ambiguity in the
interpretation of the data. Here we propose to break this limit by
using the very long baselines offered in the CHARA array. This will
test our fundamental picture and conclusively measure the innermost
dusty structure in the brightest Type 1 AGN.
