Mass estimation of massive black holes by X-ray variability with Monitor of All-sky X-ray Image, MAXI

全天x射线图像监测（MAXI）于2009年8月15日开始观测。这笔资金使我们能够准备地面计算机及其分析软件。自2009年12月起，MAXI数据通过互联网向全世界开放。从发射到现在，MAXI已经正常运行了3年零9个月。MAXI已经在高星系区探测到502个通量为>.6 mCrab的x射线源。MAXI还探测到来自14个塞弗特星系的显著功率谱。然而，由于探测器的数量是计划的一半，观测时间是一半，数据

Monitor of All-sky X-ray Image (MAXI) started the observation on 2009 August 15. This fund enabled us to prepare ground computers and their analysis software. MAXI data are open to world-wide through the internet since 2009 December. MAXI is being operated properly now for 3 years and 9 months after the launch. MAXI has detected 502 X-ray sources with flux > 0.6 mCrab in the high galactic region. MAXI also detected significant power spectra from 14 Seyfert galaxies. However, because the number of detectors is a half of the planned and the observation time is a half, the da
