An Obscured Tidal Disruption Event Uncovered by Its Mid- and Near-Infrared Dust Echo in a Star-Forming Galaxy
Hui Liu, Luming Sun, Ning Jiang +8
We present a comprehensive study of an infrared (IR) flare in the star-forming galaxy SDSS J010320.39+140152.5, which is selected from the sample of mid-IR (MIR) outbursts in nearb…
Local Analogs of Little Red Dots: Optical Variability and Evidence for an Active Galatic Nucleus Origin
Ruqiu Lin, Zhen-Ya Zheng, Junxian Wang +9
Little red dots (LRDs) draw extensive attention because of their unique observational characteristics and apparent overabundance in the early Universe, raising new insights into ea…
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…
Resolving the Nuclear Environments of Tidal Disruption Event Host Galaxies within 45 pc
Megan Newsome, Iair Arcavi, K. Decker French +5
Using HST/STIS observations, we present the highest-spatial-resolution spectroscopic study to date of four tidal disruption event (TDE) host galaxies, with the best observed being…
Discovery of the Hybrid Response of Photoionized Gases
Zhicheng He, Tinggui Wang, Gary J. Ferland
Photoionized gases are prevalent throughout the universe. In such gases, the ion concentration typically exhibits two response modes to radiation: a positive response in the low-io…
Discovery of the Asymmetric Effect in the Response of Photoionization Gas
Zhicheng He, Tinggui Wang
The variability of quasar radiation provides a powerful probe of the photoionization response of ionized gas, which plays a central role in tracing cosmic evolution and plasma phys…
