Description
HI Intensity Mapping (HIIM) as a probe of cosmological large-scale structures (LSS) is considered promising and has been test with cross-correlation with optical galaxy survey using Green Bank Telescope (GBT) and Parkes Telescope. MeerKAT and SKA have the potential to achieve largest and deepest HIIM survey in the near future. However, HIIM is also most challenging due to the bright foreground emission and instrumental effect. We proposed a pilot survey with MeerKAT array to test our data analysis pipeline. In the meanwhile, we also measured the instrumental noise feature, such as 1/f noise, by tracking the South Celestial Pole (SCP). With the noise feature measurement, we can build the noise model for the future HIIM survey with MeerKAT.
