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…

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…
