| dc.description.abstract | 測量超大質量黑洞鄰近之吸積率，可以由觀測上給出對於吸積流模型之限制，也能探討相對論性噴流的動力機制。此論文聚焦於低亮度活躍星系核(low-luminosity active galactic nuclei)，其低亮度被視為是由於其超大質量黑洞之吸積流為低輻射效率。藉由次毫米波陣列望遠鏡測量了天鵝座A 之核心在毫米波段之偏振輻射。在此觀測中，基於天鵝座A 之偏振性質在統計上缺乏有效之測量值，藉由去偏振化機制、軔致輻射吸收之探討及半解析平流主導吸積流光譜能量分佈之擬和，計算出旋轉量(rotation measure)、吸積率(the mass accretion)、以及吸積功率(accretion power) 之觀測下限值。並由此觀測得到排除對流主導吸積流模型之結論。 | zh_TW |
| dc.description.abstract | Unveiling the nature of accretion process onto the supermassive black hole (SMBH) is one of the primary purposes in modern high energy astrophysics. Constraining mass accretion rate (M ̇ ) can not only clarify the features of in- flow but also connect to the dynamics of outflow. In this dissertation, we concentrate on the low-luminosity active galactic nuclei (LLAGN) of Cygnus A, which are thought to be powered by radiatively inefficient accretion flow (RIAF). Faraday rotation measure (RM), the tracer of plasma density, pro- vides a powerful tool that can be used to investigate the mass accretion rate near the SMBH of LLAGN. We present the polarimetric observation results towards Cygnus A utilizing Submillimeter Array at 230 GHz and obtain the observational constraint on RM. With the scenarios of beam/bandwidth de- polarization and advection-dominated accretion flow model fitting, the mass accretion rate and the accretion type of Cygnus A can be constrained, and the convection-dominated accretion flow solution is excluded. | en |
