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.…
Dust-obscured radio-emitting tidal disruption event coincident with a high-energy neutrino event
Tianyao Zhou, Xinwen Shu, Guobin Mou +14
Despite the growing number of high-energy neutrinos (TeV-PeV) detected by IceCube, their astrophysical origins remain largely unidentified. Recent observations have linked a few ti…
Outflow-cloud interaction as the possible origin of the peculiar radio emission in the tidal disruption event AT2018cqh
Lei Yang, Xinwen Shu, Guobin Mou +9
AT2018cqh is a unique optical tidal disruption event (TDE) discovered in a dwarf galaxy exhibiting delayed X-ray and radio flares. We present the results from high-resolution VLBA…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
Unveiling the Cosmic Dance of Repeated Nuclear Transient ASASSN-14ko: Insights from Multiwavelength Observations
Shifeng Huang, Tinggui Wang, Ning Jiang +15
ASASSN-14ko is a periodically repeating nuclear transient. We conducted high-cadence, multiwavelength observations of this source, revealing several recurrent early bumps and rebri…
