Weak lensing with radio continuum surveys
Patel
Show how the larger radio facilities such as SKA can produce game changing cosmological measurements compared to future optical telescopes; also discuss how radio surveys can also provide unique ways in which some of the most problematic systematic errors can be mitigated through the extra information that can be provided in the form of polarization and rotational velocity measurements. Also demonstrate the advantages to having overlapping optical and radio WL surveys and how their cross-correlation leads to a cleaner extraction of the cosmo information. Key to the realization of the great promise of radio WL is the suitable measurements of galaxy shapes in the radio data, either from images or from the visibility data. End with a description of the key issues related to this matter and the radioGREAT challenge which has been proposed to address them.
