Estimating constraints on cosmological parameters via the canonical and the differential redshift drift with SKA HI 21-cm observations
Jiangang Kang, Guangyuan Song, Tong Jie Zhang +1
Redshift drift effect, an observational probe that indenpendent of cosmological models, presents unique applications in specific cosmological epoch. By quantifying redshift drift s…
Redshift drift effect through the observation of HI 21cm signal with SKA
Jiangang Kang, Tong-Jie Zhang, Peng He +1
This study presents the findings of using the Square Kilometre Array (SKA) telescope to measure redshift drift via the HI 21cm signal, employing semi-annual observational interval…
Toward a direct measurement of the cosmic acceleration: The pilot observation of H I 21cm absorption line at FAST
Jiangang Kang, Chang-Zhi Lu, TongJie Zhang +1
This study presents results on detecting neutral atomic hydrogen (HI) 21cm absorption in the spectrum of PKS1413+135 at redshift . The observation was conducted by FA…
Statistical distribution of HI 21cm intervening absorbers as potential cosmic acceleration probes
Chang-Zhi Lu, Tingting Zhang, Tong-Jie Zhang
Damped Lyman- Absorber (DLA), or HI 21cm Absorber (H21A), is an important probe to model-independently measure the acceleration of spectroscopic velocity () via th…
Toward a direct measurement of the cosmic acceleration: the first preparation with FAST
Chang-Zhi Lu, Kang Jiao, Tingting Zhang +2
Damped Lyman- Absorber(DLA) of HI 21cm system is an ideal probe to directly measure cosmic acceleration in real-time cosmology via Sandage-Loeb(SL) test. During short observatio…
