Title: Cosmology from Clusters in UNIONS
Presenter: James Taylor
Abstract:
We have recently shown that measurements of the `infall zone' around galaxy clusters can constrain the cosmological parameters omega_matter and sigma_8. We will show the results of applying this test to a cluster sample in the UNIONS survey, and also discuss the galaxy content and structural properties of the relaxed and unrelaxed parts of the sample.
