Galaxy redshift surveys are powerful as dark energy probes, as they can allow us to measure the cosmic expansion history through the measurement of Baryon Acoustic Oscillations (BAO) and the growth history of cosmic structure through the measurement of Redshift Space Distortions (RSD) in the galaxy distribution. I will talk about the measurement of large-scale structure, mainly focusing on how to extract the redshift information of galaxy clustering from BOSS and eBOSS surveys. Besides, I will show you some cosmological implications using the measured BAO and RSD, and also other astronomical data.
