Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Parameter inference with estimated covariance matrices
Elena Sellentin, Alan F. Heavens
When inferring parameters from a Gaussian-distributed data set by computing a likelihood, a covariance matrix is needed that describes the data errors and their correlations. If th…
Hierarchical Cosmic Shear Power Spectrum Inference
Justin Alsing, Alan Heavens, Andrew H. Jaffe +3
We develop a Bayesian hierarchical modelling approach for cosmic shear power spectrum inference, jointly sampling from the posterior distribution of the cosmic shear field and its…
An accurate halo model for fitting non-linear cosmological power spectra and baryonic feedback models
Alexander Mead, John Peacock, Catherine Heymans +2
We present an optimized variant of the halo model, designed to produce accurate matter power spectra well into the non-linear regime for a wide range of cosmological models. To do…
