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…

A new analytical approximation of luminosity distance by optimal HPM-Padé technique
Bo Yu, Jian-Chen Zhang, Tong-Jie Zhang +1
By the use of homotopy perturbation method-Padé (HPM-Padé) technique, a new analytical approximation of luminosity distance in the flat universe is proposed, which has the advantag…
