Toward a direct measurement of the cosmic acceleration: The first preparation with FAST
Damped Lyman-α Absorber (DLA) of HI 21 cm system is an ideal probe to directly measure cosmic acceleration in real-time cosmology via Sandage–Loeb (SL) test. During short observations toward two DLAs in the commissioning progress of FAST, we manage to exhibit an HI 21 cm absorption feature from PKS1...
