Photoionization of the Composite Nebula Surrounding NGC 5408 X-1: Implications for Beamed Emission
Jing Guo, Hua Feng, Roberto Soria +4
NGC 5408 X-1 is one of the best studied ultraluminous X-ray sources (ULXs) and is surrounded by a photoionized nebula. Previous optical spectroscopy established the presence of str…
Probing the Strong Gravity Region of Black Holes with eXTP
Qingcui Bu, Cosimo Bambi, Lijun Gou +42
We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…
Hardness Ratio Estimation in Low Counting X-ray Photometry
Y. K. Jin, S. N. Zhang, J. F. Wu
Hardness ratios are commonly used in X-ray photometry to indicate spectral properties roughly. It is usually defined as the ratio of counts in two different wavebands. This definit…
Statistical Analysis of Point-like Sources in Chandra Galactic Center Survey
J. F. Wu, S. N. Zhang, F. J. Lu +1
{\it Chandra} Galactic Center Survey detected X-ray point-like sources in the sky region around the Galactic Center. In this paper, we stu…
