耀变体的光变和光谱观测及中心黑洞的研究

Many physics are contained in broad band spectral energy distribution (SED) of active galactic nuclei (AGNs). By monitoring Gamma-noise blazar samples, firstly, to explore the rapid optical variability on timescales of hours, and then to estimate masses of the central black holes basing on Kerr black hole theory。 Secondly, by the monitoring of blazar periodic variabilityies on a medium timescale, and then explore their nature of the jet; At the same time taking advantage of 2MASS, X-satellite and Fermi database information, to analyze multi-band observational data of Blazar source. We will constrain the location of emission reigon by modeling broad band SED, and then study the relation between black mass and the emission region location. Depending on blazars as a breakthrough, to explore symbiosis and coupling of accretion disk and jet of active galactic nuclei (AGNs), to investigate high-energy gamma radiation mechanism and the central configurations of AGNs.

活动星系核的多波段辐射及其光变包含着诸多物理信息。本项目将以Gamma噪Blazar为样本，通过监测，首先要探索其小时量级的快速光变，用Kerr黑洞的理论估计其中心黑洞的质量；其次通过监测其中等时标的周期光变，进而探索其喷流的性质；与此同时将利用日益增加的高质量多波段数据通过能谱拟合的办法限制辐射区位置，进而研究辐射区位置和黑洞质量的关系。以Blazar为突破口，探讨活动星系核吸积盘和喷流的耦合及共生问题，探索活动星系核的高能Gamma辐射机制和中心结构。
