Are "Changing-Look'' Active Galactic Nuclei Special in the Coevolution of Supermassive Black Holes and their Hosts? I
J. Wang, W. K. Zheng, T. G. Brink +5
The nature of the so-called ``changing-look'' (CL) active galactic nucleus (AGN), which is characterized by spectral-type transitions within ~yr, remains an open question.…
Flaring-associated Complex Dynamics in Two M-dwarfs Revealed by Fast, Time-resolved Spectroscopy
J. Wang, H. L. Li, L. P. Xin +11
Habitability of an exoplanet is believed to be profoundly affected by activities of the host stars, although the related coronal mass ejections (CMEs) are still rarely detected in…
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…
Detection of Flare-associated CME Candidates on Two M-dwarfs by GWAC and Fast, Time-resolved Spectroscopic Follow-ups
J. Wang, L. P. Xin, H. L. Li +8
The flare-associated stellar coronal mass ejection (CME) in solar-like and late type stars is quite essential for the habitability of an exoplanet. In this paper, we report detecti…
A mag Super Flare of An Ultracool Star Detected by System
L. P. Xin, H. L. Li, J. Wang +21
In this paper, we report the detection and follow-ups of a super stellar flare GWAC\,181229A with an amplitude of 9.5 mag on a M9 type star by and the de…
