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 of AGN. In type 2 AGN, is seen roughly edge-on, leading to obscuration radiation source a silicate absorption feature near $10~{\rm\mu m}$. While most current models distribute smoothly, there growing evidence that must be arranged in clouds. We describe a new method for modeling near- mid-infrared emission 3-dimensional clumpy tori using Monte Carlo simulations . calculate fields individual clouds at various distances from AGN these within region. The properties their distribution are determined a theoretical approach self-gravitating close shear limit a gravitational potential. demonstrate clumpiness AGN tori can overcome problem over-pronounced silicate features. Finally, we present model calculations prototypical Seyfert 2 galaxy compare them recent high-resolution measurements. Our able reproduce both SED interferometric mid-infrared.
