Spectra of three-dimensional magnetized accretion flows

We examine if three-dimensional (31)) magnet-hydrodynamical (MHD) accretion flow, which is proposed as a model for low-luminosity active galactic nuclei (LLAGNs) and Galactic black hole candidates (BHCs), can reproduce the observed data of Sagittarius A* (Sgr A*). The emergent spectra are calculated by the Monte Carlo radiative transfer simulations. It is found that the 3D MHD How is successful in reproducing the basic properties of the observed spectrum of Sgr A* on the condition that the emission from the innermost part of the flow (r < 10r(s)) is dominant, where r(s) is the Schwarzschild radius.
