We study the broad-band spectral energy distribution (SED) of theprototypical low-mass active galactic nucleus (AGN) in NGC 4395. We jointlymodel the optical through mid-infrared SED with a combination of galaxy and AGNlight, and find that on arcsecond scales, the AGN dominates at mostwavelengths. However, there is still some ambiguity about emission from thegalaxy, owing partially to the strong short-term variability of the black hole.We investigate the use of smooth and clumpy-torus models in order todisentangle the nuclear infrared emission, as well as exploring the use ofpoloidal wind emission to account for the blue spectral slope observed in thenear-IR. Even when simultaneously fitting the full optical-IR spectral range,we find that degeneracies still remain in the best-fit models. We conclude thathigh spatial resolution and wider wavelength coverage with the James Webb SpaceTelescope is needed to understand the mid-infrared emission in this complexhighly-variable object, which is the best nearby example to provide a blueprintto finding other low-mass AGN via their mid-infrared emission in the future.
