A RELHIC twin candidate near the galaxy M51

Qingze Chen, Jie Wang, Yingjie Jing +7

We report the discovery of a pair of H I clouds near M51 (NGC 5194) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These clouds have no optical counterpart…

The FAST HI 21-cm Absorption Blind Survey. III. OH Absorption Search in the 21-cm Absorber Sample and Continued HI Absorption Search

Wenkai Hu, Yougang Wang, Jeremy Darling +11

We present the first blind search for OH 18-cm absorption with the Five-hundred-meter Aperture Spherical Telescope (FAST), conducted alongside the HI 21-cm absorption search. Our p…

HiFAST: An HI data calibration and imaging pipeline for the FAST IV: The stray-radiation correction

Qingze Chen, Jie Wang, Yingjie Jing +12

Stray radiation is a considerable challenge for radio telescopes, requiring careful assessment due to its effects. This is crucial when the strong background flux from side lobes s…

Nonlinear reconstruction of general dark energy theories

Yunhao Gao, Baojiu Li, Jie Wang

The large variety and number of dark energy (DE) theories make it impractical to perform detailed analyses on a case-by-case basis, which has motivated proposals to ``parameterize"…

FEASTS Combined with Interferometry (IV): Mapping HI Emission to a limit of in Seven Edge-on Galaxies

Dong Yang, Jing Wang, Zhijie Qu +17

We present a statistical study of the neutral atomic hydrogen (HI) gas extending into the circumgalactic medium perpendicular to the disk for 7 edge-on galaxies with inclinations a…

The FAST HI 21-cm absorption blind survey. II. -- Statistic Exploration for Associated and Intervening systems

Wenkai Hu, Yougang Wang, Yichao Li +12

We present an extragalactic HI 21-cm absorption lines catalog from a blind search at z 0.35, using drift-scan data collected in 1325.6 hours by the ongoing Commensal Ra…
