Swift J1357.2-0933 underwent an episodic accretion in 2011 and provided very regular temporal and spectral evolution, making it an ideal source for exploring the nature of very fai…
Multi-frequency Radio Profiles of PSR B1133+16: radiation location and particle energy
Ji-Guang Lu, Yuan-Jie Du, Long-Fei Hao +9
The pulse profile of PSR B1133+16 is usually regarded as a conal-double structure. However, its multifrequency profiles cannot simply be fitted with two Gaussian functions, and a t…
Axion-photon Propagation in Magnetized Universe
Chen Wang, Dong Lai
Oscillations between photons and axion-like particles (ALP) travelling in intergalactic magnetic fields have been invoked to explain a number of astrophysical phenomena, or used to…
The orbital period evolution of the supersoft X-ray source CAL 87
Iminhaji Ablimit, Xiang-Dong Li
CAL 87 is one of the best known supersoft X-ray sources. However, the measured masses, orbital period and orbital period evolution of CAL 87 cannot be addressed by the standard the…
The optical identifcation of events with poorly defined locations: The case of the Fermi GBM GRB140801A

We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg 3- error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the…
Super-Strong Magnetic Fields of Neutron Stars in Be X-Ray Binaries Estimated with New Torque and Magnetosphere Models
Chang-Sheng Shi, Shuang-Nan Zhang, Xiang-Dong Li
We re-estimate the surface magnetic fields of neutron stars (NSs) in Be X-ray binaries (BeXBs) with different models of torque, improved beyond Klus et al. (2014). In particular, a…
X-ray fluorescent lines from the Compton-thick AGN in M51
Weiwei Xu, Zhu Liu, Lijun Gou +1
The cold disk/torus gas surrounding active galactic nuclei (AGN) emits fluorescent lines when irradiated by hard X-ray photons. The fluorescent lines of elements other than Fe and…
