Study of extended X-ray sources

确定了ASCA上x射线望远镜（XRT）的点扩展函数。使用ISAS的30米波束线进行了校准。我们还确定了GIS仪器的响应矩阵，这些仪器目前用于世界各地的ASCA客座观察员。我们在我们的工作站安装了用于x射线成像和光谱研究的标准软件。在plpackage标准软件中安装了点扩展函数和响应矩阵。我们利用Ginga卫星进行了大量的x射线光谱分析。我们首次探测到恒星形成区Rho-Oph和SNR IC443， HB9, IC443， RCW86和其他区域的硬x射线发射。我们对许多年轻的超新星残余物进行了系统的研究，发现它们大多处于非平衡电离状态。我们在银河系中心区域发现了大量延伸的薄热等离子体。我们还对沿星系行星的薄热等离子体进行了二维映射，在附近的室女座星系团中也发现了大量扩展的x射线发射。铁丰度在星团中呈中心峰。我们设定了星团间空间x射线表面亮度的新上限

We have determined point spread function of X-ray telescope (XRT) on board ASCA.Calibrations has been done using the 30-m beam line at ISAS.WE also determined response matrix of the GIS instruments, which are currently used for the ASCA Guest Observers in all of the worldWe have installed standard software for the study of X-ray imaging and spectra in our work station. Also point spread function and response matrix were installed in the standard soft were plpackagesX-ray spectral analysis we extensively carried out using the Ginga satellite. We have for the first times detected hard X-ray emission from the star forming region Rho-Oph and SNR IC443, HB9, IC443, RCW86 and Others. Iron K-shell emission from Star forming region of Rho-Oph, Eta-Car and Orion Nebula are discoveredWe have carried out systematic study for many young supernova remnants and found that most of them are in non-equilibrium ionization statesWe discovered largely extended thin hot plasma from the region of our galactic center. We also performed two-dimensional mapping of the thin hot plasma along the galactic planeLargely extended X-ray emission is also discovered from the near-by cluster of galaxies The Virgo Cluster. Iron abundance is found to exhibits central peak in the cluster. We have set new upper-limit of X-ray surface brightness of inter-cluster space
