Constraining clumpy dusty torus models using optimized filter sets
Abstract
Recent success in explaining several properties of the dusty torus around the central engine of active galactic nuclei has been gathered with the assumption of clumpiness. The properties of such clumpy dusty tori can be inferred by analyzing spectral energy distributions (SEDs), sometimes with scarce sampling given that large aperture telescopes and long integration times are needed to get good spatial resolution and signal. We apply the formalism of Bayesian adaptive exploration to evaluate the optimum next observation such that we maximize the constraining power of the new observed photometric point. In general, we find that the region between 10 and 200 um produces the largest increase in the expected utility, although sub-mm data from ALMA also prove to be useful. It is important to note that here we are not considering the angular resolution of the data, which is key when con- straining torus parameters. Therefore, the expected utilities derived from this methodology must be weighted with the spatial resolution of the data.
