Cosmology with MeerKAT: the MeerKLASS project
Record type:
MeerKAT's exquisite sensitivity and instrumental stability has made it an excellent medium to test cosmology. This is particularly true using the neutral hydrogen intensity mapping technique which allows MeerKAT to measure the HI distribution across the universe up to $z\sim1$ over wide areas. I will introduce MeerKLASS, a large project aimed at probing cosmology using MeerKAT single dish data, as well as producing high resolution interferometric images over vast regions of the sky. I will describe the pipelines developed and the results that have been achieved so far, including the first detections of the HI power spectrum using this technique. I will end with a discussion of the plan for the next five years, which aims to measure with high accuracy several key metrics for cosmology, such as baryon acoustic oscillations, redshift space distortions and the shape of the power spectrum on ultra large scales.
