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…
Tracing Cold Gas in Absorption Across Cosmic Time with the SKA
Elizabeth K. Mahony, Neeraj Gupta, Sergei A. Balashev +12
Observing the 21-cm HI line in absorption provides a powerful means of tracing the cold neutral gas in normal and active galaxies across cosmic time. The frequency coverage and sen…
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…
Investigating the Impacts of AGN Activities on Dwarf Galaxies with FAST HI Observations
Hong-Ying Chen, Chao-Wei Tsai, Pei Zuo +9
We present the results of Hi line observations towards 26 Active Galactic Nuclei (AGN)-hosting and one star-forming dwarf galaxies (Mstar < 10^9.5 Msun) with the 19-beam spectral l…
MeerKAT HI observations of Low Surface Brightness/Ultradiffuse Galaxy Candidates Projected around Two Southern Loose Groups
Chandreyee Sengupta, Tom C. Scott, Hao Chen +9
A large catalogue of low surface brightness galaxies (LSBGs) from the Dark Energy Survey showed significant clustering around nearby galaxy groups and clusters. Using the HIPASS su…
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.…
