Long-term Mid-infrared Color Variations of Narrow-Line Seyfert 1 Galaxies
Jiahua Wu, Huifang Xie, Liming Dou +6
We present a systematic investigation of long-term mid-infrared (MIR) color variability in 1,718 Narrow-Line Seyfert 1 galaxies (NLSy1s) using 14-year \textit{WISE}/NEOWISE monitor…
AGNs in the extremely overdense galaxy region BOSS 1441: A Chandra observation
Jiahua Wu, Liming Dou, Zheng Cai +6
We present a Chandra/ACIS-I study of X-ray sources in BOSS 1441, a protocluster at that exhibits a prominent overdensity of Ly emitters (LAEs). Using a 45 ks obs…
A Torus Remnant Revealed by the Infrared Echo of Tidal Disruption Event AT 2019qiz: Implications for the Missing Energy and Quasiperiodic Eruption Formation
Mingxin Wu, Ning Jiang, Jiazheng Zhu +3
AT 2019qiz is the first standard optical tidal disruption event (TDE) with detection of X-ray quasi-periodic eruptions (QPEs), providing strong evidence for TDE-QPE association. Mo…
The Secular Periodic Evolution of X-ray Quasi-periodic Eruptions Driven by Star-disc Collisions
Jiajun Xian, Fupeng Zhang, Liming Dou +1
We study the secular periodic evolution of quasi-periodic eruptions (QPEs) for GSN069 and eRO-QPE2 assuming that they are driven by star-disc collisions. We set up numerical simula…
An 85-s X-ray quasi-periodicity after a stellar tidal disruption by a candidate intermediate-mass black hole
Wenjie Zhang, Xinwen Shu, Luming Sun +4
It is still in dispute the existence of intermediate-mass black holes (IMBHs) with a mass of ~10^3-10^5 solar masses (Msun), which are the missing link between stellar-mass black h…
Discovery of a years-delayed radio flare from an unusually slow-evolved tidal disruption event
Zhumao Zhang, Xinwen Shu, Lei Yang +19
SDSS J1115+0544 is a unique low-ionization nuclear emission-line region (LINER) galaxy with energetic ultraviolet (UV), optical and mid-infrared outbursts occurring in its nucleus.…
