AT2021aeuk: A Repeating Partial Tidal Disruption Event Candidate in a Narrow-line Seyfert 1 galaxy
Jingbo Sun, Hengxiao Guo, Minfeng Gu +13
A black hole (BH) can tear apart a star that ventures within its tidal radius, producing a luminous flare as the stellar debris falls back, known as a tidal disruption event (TDE).…
Unprecedented Continuum Time Delay Variation Phenomenon in an Active Supermassive Black Hole
Shuying Zhou, Mouyuan Sun, Hai-Cheng Feng +12
Resolving the accretion disks and broad line regions (BLRs) of active galactic nuclei (AGNs) can probe the physics behind supermassive black holes (SMBHs) fueling and weigh SMBHs.…
Application of the space-based optical interferometer towards measuring cosmological distances of quasars
Ying-Ke Huang, Yue-Dong Fang, Kai-Xing Lu +6
Measuring the quasar distance through joint analysis of spectroastrometry (SA) and reverberation mapping (RM) observations is a new method for driving the development of cosmology.…
AGN STORM 2: I. First results: A Change in the Weather of Mrk 817
Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69
We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…
Spectroscopic Monitoring of Blazar S5 0716+714: Brightness-Dependent Spectral Behavior
Hai-Cheng Feng, Sen. Yang, Zi-Xu. Yang +17
In this paper, we report the new results of spectroscopic observations of -ray blazar S5 0716+714 from 2019 September to 2020 March with the 2.4 m optical telescope at Lijiang O…
