Description
A key point for 21cm Intensity Mapping studies in the post-reionization Universe is the subtraction of the bright foregrounds,orders of magnitude stronger than the pristine cosmological signal. In this talk, I will briefly describe the status of MeerKLASS, an Intensity Mapping survey with the MeerKAT telescope. Moreover, I will report the results of an effort, led by the SKA Intensity Mapping Focus Group, to construct a realistic mock data cube with improved sky model and instrument characterization,and to assess through simulations the performance of foreground cleaning methods. I will discuss current limitations and the roadmap to the SKAO era.
