Cosmology with extragalactic proper motions: harmonic formalism, estimators, and forecasts
Alex Hall
We conduct a thorough study into the feasibility of measuring large-scale correlated proper motions of galaxies with astrometric surveys. We introduce a harmonic formalism for anal…

A Bayesian method for combining theoretical and simulated covariance matrices for large-scale structure surveys
Alex Hall, Andy Taylor
Accurate and precise covariance matrices will be important in enabling planned cosmological surveys to detect new physics. Standard methods imply either the need for many N-body si…
