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…
The Formation of Direct Collapse Black Holes at Cosmic Dawn and 21 cm Global Spectrum
Meng Zhang, Bin Yue, Yidong Xu +1
JWST reveals numerous high-z galaxies and Supermassive Black Holes (SMBHs), suggesting that stars and SMBH seeds formation at may be more efficient than previously d…
Reconstructing the Anisotropic Ultra-long Wavelength Spectra using a Single Antenna on Lunar-orbit
Qige Ao, Furen Deng, Yidong Xu +3
The ultra-long wavelength sky ( MHz) is still largely unexplored, as the electromagnetic wave is heavily absorbed and distorted by the ionosphere on Earth. The far-si…
Loop I/NPS morphology predictions in the ultralong-wavelength band
Yanping Cong, Bin Yue, Yidong Xu +3
Loop I/North Polar Spur (NPS) is the giant arc structure above the Galactic plane observed at radio wavelengths ( GHz). There has been long-standing debate about its o…
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…
Detections of 21-cm absorption with a blind FAST survey at z 0.09
Wenkai Hu, Yougang Wang, Yichao Li +10
We present the early science results from a blind search of the extragalactic HI 21-cm absorption lines at z 0.09 with the drift-scan observation of the Five-hundred-me…
A new method of reconstructing Galactic three-dimensional structures using ultralong-wavelength radio observations
Yanping Cong, Bin Yue, Yidong Xu +2
The free-free absorption of low frequency radio waves by thermal electrons in the warm ionized medium of our Galaxy becomes very significant at MHz (ultralong-wavelen…
Impact of the turnover in the high-z galaxy luminosity function on the 21-cm signal during Cosmic Dawn and Epoch of Reionization
Zekang Zhang, Huanyuan Shan, Junhua Gu +6
The shape of the faint-end of the high-z galaxy luminosity function (LF) informs early star formation and reionization physics during the Cosmic Dawn and Epoch of Reionization. Unt…
An Ultra-long Wavelength Sky Model with Absorption Effect
Yanping Cong, Bin Yue, Yidong Xu +3
The radio sky at frequencies below MHz is still largely unknown, this remains the last unexplored part of the electromagnetic spectrum in astronomy. The upcoming space exp…
On the faint-end of the high- galaxy luminosity function
Bin Yue, Andrea Ferrara, Yidong Xu
Recent measurements of the Luminosity Function (LF) of galaxies in the Epoch of Reionization (EoR, $z\gsim6$) indicate a very steep increase of the number density of low-mass galax…
