Title: Scrutinizing AGN thermal emission at the highest spatial resolution

Abstract: AGN thermal emission is now being scrutinized at a very high angular resolution with long-baseline interferometry in the infrared. We believe that we are spatially resolving the innermost dusty structure, i.e. the dust sublimation region, quantifying the inner radial structure of AGN tori. In particular, we are getting a critical, intriguing hint that this inner radial distribution of the accreting material is closely related to the mode of the central engine. However, we are currently limited by the available baseline lengths, with which we can only marginally resolve the structure. This leaves substantial ambiguity in the interpretation of the data. Here we propose CHARA array observations to reach the highest spatial resolution ever achieved directly for the AGN thermal emission. We will test our fundamental picture and conclusively quantify the overall innermost dusty structure of AGN tori.
