模拟银河系中心的耀斑辐射

Modelling the flaring emission at the Galactic Centre

E. M. Howard

摘要:

银河系中心的大质量黑洞已知在无线电、毫米波、近红外和X射线方面是可变的。我们调查的物理过程负责的变量观测到的排放紧凑的射电源Sgr A*。我们研究的可变发射区的演变和本光变曲线和时间分辨光谱的排放从吸积盘,接近事件视界,附近的边缘稳定轨道的克尔黑洞。

英文摘要:

The massive black hole at the Galactic Centre is known to be variable in radio, millimeter, near-IR and X-rays. We investigate the physical processes responsible for the variable observed emissions from the compact radio source Sgr A*. We study the evolution of the variable emission region and present light curves and time-resolved spectra of emissions from the accretion disk, close to the event horizon, near the marginally stable orbit of a Kerr black hole.
