B3\,0749+460A: A New "Changing-Look" Active Galactic Nucleus Associated with X-ray Spectral Slope Variations
J. Wang, W. K. Zheng, D. W. Xu +5
Here we report an identification of B3\,0749+460A as a new double-peaked local "changing-look" active galactic nucleus (CL-AGN) in terms of our multi-epoch spectroscopic analysis.…
Constrains on optical emission of FAST-detected FRB 20181130B with GWAC synchronized observations
L. P. Xin, H. L. Li, J. Wang +17
Multi-wavelength simultaneous observations are essential to the constraints on the origin of fast radio bursts (FRBs). However, it is a significant observational challenge due to t…
Spectroscopy of the Type Ic Supernova SN\,2017iuk Associated with Low-redshift GRB\,171205A
J. Wang, Z. P. Zhu, D. Xu +7
We here report a spectroscopic monitor for the supernova SN\,2017iuk associated with the long-duration low-luminosity gamma-ray burst GRB\,171205A at a redshift of 0.037, which is…
A Global Photoionization Response to Prompt Emission and Outliers: Different Origin of Long Gamma-ray Bursts?
J. Wang, L. P. Xin, Y. L. Qiu +2
By using the line ratio \ion{C}{4}/\ion{C}{2} as a tracer of ionization ratio of the interstellar medium (ISM) illuminated by a long gamma-ray burst (LGRB…
The shallow-decay phase in both optical and x-ray afterglows of Swift GRB 090529A: Energy injection into a wind-type medium?
L. P. Xin, A. Pozanenko, D. A. Kann +22
The energy injection model is usually proposed to interpret the shallow-decay phase in Swift GRB X-ray afterglows. However, very few GRBs have simultaneous signatures of energy inj…
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…
