Multiband SED Observation for AGN torus
Multi-wavelength studies have been dedicated to exploring the properties of the obscuring material in active galactic nuclei (AGN). Various models have been developed to describe the structure and distribution of this material and constrain its physical and geometrical parameters through spectral fitting techniques. The various torus models make specific predictions about the emitted SED which can be compared with NIR-MIR observations and X-ray observations. I will briefly introduce recent works on the multi-wavelength SED fitting results of AGNs from X-ray to infrared band and compare the main parameters (e.g., size/scale, distribution of clouds, inclination angle, cover factor, dust temperature, clump optical depths...) of AGN torus through SED fitting.
