Evidence for Fluorescent Fe II Emission from Extended Low Ionization Outflows in Obscured Quasars
Tinggui Wang, Gary Ferland, Chenwei Yang +2
Recent studies have shown that outflows in at least some broad absorption line (BAL) quasars are extended well beyond the putative dusty torus. Such outflows should be detectable i…
Long Fading Mid-Infrared Emission in Transient Coronal Line Emitters: Dust Echo of Tidal Disruption Flare
Liming Dou, Ting-gui Wang, Ning Jiang +3
The sporadic accretion following the tidal disruption of a star by a super-massive black hole (TDE) leads to a bright UV and soft X-ray flare in the galactic nucleus. The gas and d…
The WISE Detection of an Infrared Echo in Tidal Disruption Event ASASSN-14li
Ning Jiang, Liming Dou, Tinggui Wang +3
We report the detection of a significant infrared variability of the nearest tidal disruption event (TDE) ASASSN-14li using Wide-field Infrared Survey Explorer} and newly released…
