Constraining cosmology using galaxy position angle-only cosmic shear

Lee Whittaker

We investigate cosmological parameter inference from realistic simulated weak lensing image data using only galaxy position angles, as opposed to full-ellipticity information. We d…

Exact joint likelihood of pseudo- $C_{ℓ}$ estimates from correlated Gaussian cosmological fields

Robin E. Upham, Lee Whittaker, Michael L. Brown

We present the exact joint likelihood of pseudo- $C_{ℓ}$ power spectrum estimates measured from an arbitrary number of Gaussian cosmological fields. Our method is applicable to bot…
