NGC 3227 Blinks: An Extreme Changing-Look Event in a Seyfert Galaxy
Kaiwen Zhang, Michael S. Brotherton, Pu Du +10
We report a rapid optical changing-look event in the Seyfert galaxy NGC 3227: the optical continuum faded by more than 70% and broad H-beta emission nearly disappeared within weeks…
On the Orbital Evolution of Giant Planet Pair Embedded in a Gaseous Disk. III. simultaneous gas accretion and the final mass ratio
Bixuan Zhao, Hui Zhang, Yinhao Wu +1
Recent exoplanet surveys reveal a systematic trend in the mass ratios of giant planet pairs (). Although the is broadly centered near unity, it…
Antarctic TianMu Staring Observation Project I: Overview and Implementation of the Prototype Telescope
Dan Zhou, Jing Zhong, Jianchun Shi +31
Wide-field rapid sky surveys serve as critical observational methods for time-domain astronomical research. The Antarctic region, with several months of continuous dark nights annu…
Monitoring AGNs with H Asymmetry. V. Long-term Variation and Evolution of the Broad H Emission-Line Profiles
Feng-Na Fang, Pu Du, Michael S. Brotherton +40
The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal varia…
Multi-Wavelength Monitoring and Reverberation Mapping of a Changing Look Event in the Seyfert Galaxy NGC 3516
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +26
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC 3516 carried out in 2018 to 2020 covering the wavelength range from the X-…
