GRO J1655-40: from ASCA and XMM-Newton Observations
Xiao-Ling Zhang, Shuang Nan Zhang, Gloria Sala +3
We have analysed four ASCA observations (1994--1995, 1996--1997) and three XMM-Newton observations (2005) of this source, in all of which the source is in high/soft state. We model…
Studying the Properties of Accretion Disks and Coronae in Black Hole X-ray Binaries with Monte-Carlo Simulations
Yangsen Yao, S. Nan Zhang, Xiaoling Zhang +2
Understanding the properties of the hot corona is important for studying the accretion disks in black hole X-ray binary systems. Using the Monte-Carlo technique to simulate the inv…
A New Method to Use Chandra Data to Resolve the X-Ray Halos Around Point Sources and Its Application to Cygnus X-1
Y. Yao, S. Nan Zhang, X. L. Zhang +1
With excellent angular resolution, good energy resolution and broad energy band, the Chandra ACIS is the best instrument for studying the X-ray halos around some galactic X-ray poi…
Relativistic Effects on the Appearance of a Clothed Black Hole
Xiaoling Zhang, S. Nan Zhang, Yuxin Feng +1
For an accretion disk around a black hole, the strong relativistic effects affect every aspect of the radiation from the disk, including its spectrum, light-curve, and image. This…
A Peculiar Flaring Episode of Cygnus X-1
Wei Cui, Yuxin Feng, Mark Ertmer
Recent monitoring of Cyg X-1 with {\em RXTE} revealed a period of intense flaring, which started in October of 2000 and lasted until March of 2001. The source exhibited some quite…
