SN 2023fyq: direct detection of a Type Ibn supernova progenitor and its multi-wavelength environmental constraints
Xinyi Hong, Ning-Chen Sun, Yali Shao +9
Context. Type Ibn supernovae (SNe) are characterized by narrow helium emission lines arising from ejecta-circumstellar medium interaction, yet their progenitors remain debated, wit…
Two kinds of Galactic source populations could explain the cosmic-ray observation up to the "knee" region
Furong Li, Wei Liu, Yali Shao +1
Observations of diffuse gamma rays above hundreds of TeV from the Galactic disk provide strong evidence for the existence of PeV cosmic-ray accelerators--so-called PeVatrons--in th…
(SHERRY) JCMT-SCUBA2 High Redshift Bright Quasar Survey -- II: the environment of z~6 quasars in sub-millimeter band
Qiong Li, Ran Wang, Xiaohui Fan +14
The formation of the first supermassive black holes is expected to have occurred in some most pronounced matter and galaxy overdensities in the early universe. We have conducted a…
Constraining the excitation of molecular gas in Two Quasar-Starburst Systems at
Fuxiang Xu, Ran Wang, Jianan Li +15
We present NOrthern Extended Millimeter Array observations of CO(8-7), (9-8), and (10-9) lines, as well as the underlying continuum for two far-infrared luminous quasars: SDSS J205…
