Her X-1: the positive cyclotron line energy / luminosity correlation
pulsars: individual: – stars: neutron – stars: binaries
2011/9/28
Studies of some bright, super-Eddington transient pulsars show a negative correlation between the energy of the cyclotron resonance scattering feature (CRSF) and the bolometric luminosity. For Her X-1...
Jets in high-mass microquasars
X-rays: binaries–ISM: jets and outfl ows–Stars: winds, outfl ows–Radiation mechanisms: non-thermal
2011/9/28
The morphologies of detected jets in X-ray binaries are almost as diverse as their number. This is due to different jet properties and ambient media that these jets encounter. It is important to under...
{\it Suzaku} observation of Galactic supernova remnant CTB 37A (G348.5+0.1)

2011/9/28
We present here the results of the observation of CTB 37A obtained with the X-ray Imaging Spectrometer onboard the {\it Suzaku} satellite. The X-ray spectrum of CTB 37A is well fitted by two component...
The inverse-Compton ghost HDF 130 and the giant radio galaxy 6C 0905+3955: matching an analytic model for double radio source evolution
galaxies: individual: RGJ123617/HDF130, 6C0905+3955 – galaxies: evolution – galaxies: jets – radio continuum: galaxies – X-rays: galaxies.
2011/9/28
We present new GMRT observations of HDF 130, an inverse-Compton (IC) ghost of a giant radio source that is no longer being powered by jets. We compare the properties of HDF 130 with the new and import...
Suzaku Discovery of Twin Thermal Plasma from the Tornado Nebula
ISM: individual (G357.7− 0.1)—ISM: jets and outfl ows—X-ray:ISM
2011/9/28
The Tornado nebula (G357.7-0.1) is a mysterious radio source with bright "head" and faint "tail" located in the direction of the Galactic center (GC) region. We here report the discovery of two diffus...
The Core-like Nature of HST-1 in the M87 Jet

脉冲星具有自转非常稳定的特性,在空间自主导航中有重要的应用前景。选择和研究一组适合于脉冲星导航使用的候选目标源非常重要,决定脉冲星导航精度的主要因素有:导航目标源X射线流量强度、目标源的位置精度和旋转参数精度。对可用于导航的一些X射线源进行了讨论研究,并对最适合做导航研究的转动能驱动的X射线脉冲星进行统计分析。
中子星X射线双星中kHz QPO现象的理论解释
X射线双星 吸积 中子星 千赫兹准周期振荡(kHz QPO)
2012/9/12
罗西X射线时变探测器(RXTE)在中子星小质量X射线双星中发现了千赫兹准周期振荡现象(kHzQPO)。kHzQPO的频率一般在几百到上千赫兹,其动力学时标与吸积盘最内部区域物质的运动时标一致,因此普遍认为kHz QPO产生于中子星表面附近区域,携带了来自中心中子星及周围强引力场信息,如质量、自转周期、角动量、半径、磁场等。kHz QpO现象的理解为研究强引力场和致密物质状态开启了一扇新的窗口。着重...
