Physics of the Central Engines of Active Galactic Nuclei

强有力的论据支持这样的观点，即物质的相互作用 与一个超大质量黑洞的碰撞， 与活动星系核（AGN）有关的现象。 然而，这些相互作用的细节知之甚少。 理论研究旨在加深我们对 黑洞吸积的微观物理学，喷流的形成， 活动星系核中负责光谱形成的过程 执行。 使用分析和数值技术， 研究内容包括：1）气体的热态 活动星系核的中心发动机及其对 活动星系核光谱; 2）电子-正电子对产生的作用， 活动星系核光谱产生的其他高能过程; 辐射阻力对磁流体加速度的影响 相对论性喷流和风;以及4）辐射特征 形成射流。 通过携带活动星系核， 观察的解释。

Strong arguments support the view that interactions of matter with a supermassive black hole give rise to the diverse phenomena associated with active galactic nuclei (AGNs). However, the details of these interactions are poorly understood. Theoretical research aimed at augmenting our understanding of the microphysics of accretion onto black holes, jet formation, and the processed responsible for spectrum formation in AGNs will be carried out. Using analytic and numerical techniques, the following will be studied: 1) the thermal states of gas in the central engines of AGNs and their effects on the production of AGN spectra; 2) the roles of electron-positron pair creation and other high energy processes in the production of AGN spectra; 3) the effects of radiation drag on the hydromagnetic acceleration of relativistic jets and winds; and 4) the radiative signatures of jet formation. Through carrying AGNs, and facilitate the interpretation of observations.
