Title: Cosmology with MeerKAT and the SKA
Abstract:
The next generation of radio telescopes will open a new observational window for cosmology. In particular, SKA1-MID, to be set in South Africa, has the potential to measure the equation of state of dark energy out to z~3, constrain possible deviations from General Relativity or provide transformational measurements of the structure of the Universe on the largest accessible scales, thus constraining fundamental properties such as isotropy, homogeneity, and non-Gaussianity. Moreover, MeerKAT, already in operation, will already be able to provide cosmological constraints, in particular the detection of Baryon Acoustic Oscillations using the HI intensity mapping technique. I will describe the cosmological surveys planned for SKA1-MID as well as what can be achieved with a large survey using MeerKAT.
