Radiative Transfer Modeling of Three-Dimensional Clumpy AGN Tori and its Application to NGC 1068

摘要: Recent observations of NGC 1068 and other AGN support the idea a geometrically optically thick dust torus surrounding central supermassive black hole accretion disk AGN. In type 2 AGN, is seen roughly edge-on, leading to obscuration radiation source silicate absorption feature near 10 micron. While most current models distribute smoothly, there growing evidence that must be arranged in clouds. We describe new method for modeling near- mid-infrared emission 3-dimensional clumpy tori using Monte Carlo simulations. calculate fields individual clouds at various distances from these within region. The properties their distribution are determined theoretical approach self-gravitating close shear limit gravitational potential. demonstrate clumpiness can overcome problem over-pronounced features. Finally, we present model calculations prototypical Seyfert galaxy compare them recent high-resolution measurements. Our able reproduce both SED interferometric mid-infrared.
