Radio and X-ray flux rebrightening six years after outburst in a partially-obscured extreme changing-look AGN
Tianyao Zhou, Xinwen Shu, Lei Yang +14
The paper reports multi‑year observations of the partially obscured AGN SDSS J1548+2208, revealing sustained high mid‑infrared and hard X‑ray fluxes and a late‑time radio rebrighte…

AT2019ijn: a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission
Hucheng Ding, Xinwen Shu, Luming Sun +9
We report the discovery of a peculiar optical transient, AT2019ijn, occurred in the nuclear region of a dwarf galaxy at z=0.273. It rises rapidly to peak at a luminosity of Mg=-21.…

A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
