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.
