Jin Zhang, J. M. Bai, Liang Chen +1
The observed radio-optical-X-ray spectral energy distributions (SEDs) of 22 hot spots and 45 knots in the jets of 35 active galactic nuclei are complied from literature and modeled…
The emission positions of kHz QPOs and Kerr spacetime influence
C. M. Zhang, Y. C. Wei, H. X. Yin +5
Based the Alfven wave oscillation model (AWOM) and relativistic precession model (RPM) for twin kHz QPOs, we estimate the emission positions of most detected kHz QPOs to be at r=18…
Adiabatic Perturbations in Homologous Conventional Polytropic Core Collapses of a Spherical Star
Yi Cao, Yu-Qing Lou
We perform a non-radial adiabatic perturbation analysis on homologous conventional polytropic stellar core collapses. The core collapse features a polytropic exponent relat…
Simulations on High-z Long Gamma-Ray Burst Rate
Shu-Fu Qin, En-Wei Liang, Rui-Jing Lu +2
Since the launch of Swift satellite, the detections of high-z (z>4) long gamma-ray bursts (LGRBs) have been rapidly growing, even approaching the very early Universe (the record ho…
Microlensing pulsars
S. Dai, R. X. Xu, A. Esamdin
We investigate the possibilities that pulsars act as the lens in gravitational microlensing events towards the galactic bulge or a spiral arm. Our estimation is based on expectant…
Lower bounds of altitudes for pulsar -ray radiation
K. J. Lee, Y. J. Du, H. G. Wang +3
Determining radiation location observationally plays a very important role in testing the pulsar radiation models. One-photon pair production in the strong magnetic field, $γ-e^{+}…
Discovery of a magnetic neutron star in X-ray transient IGR J01583+6713
W. Wang
IGR J01583+6713 is a new transient source discovered by the INTEGRAL/IBIS hard X-ray surveys. Optical observations suggested that it should be a high mass X-ray binary, but its nat…
Mechanism of very high energy radiation in BL Lacertae object 3C 66A
Jianping Yang, Jiancheng Wang
Our goal is to understand the nature of blazars and the mechanisms for the generation of high-energy -rays, through the investigation of the blazar 3C 66A. We model the high ene…
Characteristic velocities of stripped-envelope core-collapse supernova cores
I. Maurer, P. A. Mazzali, J. Deng +9
The velocity of the inner ejecta of stripped-envelope core-collapse supernovae (CC-SNe) is studied by means of an analysis of their nebular spectra. Stripped-envelope CC-SNe are th…
GRB 070518: A Gamma-ray Burst with Optically Dim Luminosity
L. P. Xin, W. K. Zheng, J. Wang +6
We present our optical observations of {\em Swift} GRB 070518 afterglow obtained at the 0.8-m Tsinghua University-National Astronomical Observatory of China telescope (TNT) at Xing…
The hard to soft spectral transition in LMXBs - affected by recondensation of gas into an inner disk
E. Meyer-Hofmeister, B. F. Liu, F. Meyer
Soft and hard spectral states of X-ray transient sources reflect two modes of accretion, accretion via a geometrically thin, optically thick disk or an advection-dominated accretio…
Application of the Disk Evaporation Model to AGNs
B. F. Liu, Ronald E. Taam
The disk corona evaporation model extensively developed for the interpretation of observational features of black hole X-ray binaries (BHXRBs) is applied to AGNs. Since the evapora…
Polarization Changes of Pulsars due to Wave Propagation Through Magnetospheres
Chen Wang, Dong Lai, JinLin Han
We study the propagation effects of radio waves in a pulsar magnetosphere, composed of relativistic electron-positron pair plasmas streaming along the magnetic field lines and coro…
