Combining weak lensing tomography and spectroscopic redshift surveys
Yan-Chuan Cai, Gary Bernstein
Redshift space distortion (RSD) is a powerful way of measuring the growth of structure and testing General Relativity, but it is limited by cosmic variance and the degeneracy betwe…
Lossy compression of weak lensing data
R. Ali Vanderveld, Gary M. Bernstein, Chris Stoughton +4
Future orbiting observatories will survey large areas of sky in order to constrain the physics of dark matter and dark energy using weak gravitational lensing and other methods. Lo…
Cosmology without cosmic variance
Gary M. Bernstein, Yan-Chuan Cai
We examine the improvements in constraints on the linear growth factor G and its derivative f=d ln G / dln a that are available from the combination of a large-scale galaxy redshif…
Optimizing weak lensing mass estimates for cluster profile uncertainty
Daniel Gruen, Gary M. Bernstein, Tsz Yan Lam +1
Weak lensing measurements of cluster masses are necessary for calibrating mass-observable relations (MORs) to investigate the growth of structure and the properties of dark energy.…
