Suspended and restored activities of A Nearby Super Massive Black Hole
J. Wang, D. W. Xu, S. S. Sun +4
The discovery of spectral type transition of active galactic nuclei (AGNs), the so-called changing-look(CL) phenomenon, challenges the widely accepted AGN paradigm, not only in the…
A Pilot Study of Catching High- GRBs and Exploring Circumburst Environment in the Forthcoming SVOM Era
J. Wang, Y. L. Qiu, J. Y. Wei
Rapid spectroscopy of GRB afterglows is an important and hard task. Based on the archival XS-GRB spectral database, we here perform a pilot study on the afterglow's spectroscopy in…
Photometric and spectroscopic Studies of Superoutbursts of Three Dwarf Novae Independently Identified by The SVOM/GWAC System in 2018
J. Wang, H. L. Li, L. P. Xin +27
We report our photometric and spectroscopic follow-up observations of the superoutbursts of three dwarf novae (GWAC\,180415A, GWAC\,181017A and GWAC\,181211A) identified independen…
Two New "Turn-off" Changing-look Active Galactic nuclei and Implication on "Partially Obscured" AGNs
J. Wang, D. W. Xu, Y. Wang +3
We here report a spectroscopic identification of two new changing-look AGNs (CL-AGNs): SDSS\,J104705.16+544405.8 and SDSS\,J120447.91+170256.8 both with a "turn-off" type transitio…
Learning Transient Universe in Near-Ultraviolet By Wide-angle Cameras
J. Wang, E. W. Liang, J. Y. Wei
We perform a detailed analysis and simulations on the transient detection capability in the near-ultraviolet (NUV) band by focusing on some major local transient events. These even…
A Correlated Study of Optical and X-ray Afterglows of GRBs
Liang Li, Xue-Feng Wu, Yong-Feng Huang +10
We study an extensive sample of 87 GRBs for which there are well sampled and simultaneous optical and X-ray light-curves. We extract the cleanest possible signal of the afterglow c…
