To date weak gravitational lensing surveys have typically been restricted to small fields of view, such that the flat-sky approximation has been sufficiently satisfied. However, with Stage IV surveys (e.g. LSST and Euclid) imminent, extending mass-mapping techniques to the sphere is a fundamental necessity. As such, we extend the sparse hierarchical Bayesian mass-mapping formalism presented in previous work to the spherical sky. For the first time, this allows us to construct maximum a…

Higher order statistics of shear field: a machine learning approach
TLDR
This work investigates the development of a new method to treat weak lensing higher order statistics, which are known to break degeneracy among cosmological parameters thanks to their capability of probing the non-Gaussian properties of the shear field.
Sparse image reconstruction on the sphere: a general approach with uncertainty quantification
TLDR
This article considers the Bayesian interpretation of the unconstrained problem which, combined with recent developments in probability density theory, permits rapid, statistically principled uncertainty quantification (UQ) in the spherical setting and linearity is exploited to significantly increase the computational efficiency of such UQ techniques.
Bayesian variational regularization on the ball
TLDR
Variational regularization methods which leverage sparsity-promoting priors to solve severely illposed inverse problems defined on the 3D ball and thus does not suffer from discontinuities that plague alternate approaches where each spherical shell is considered independently.
Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction
We present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted projections of the density…
Posterior sampling for inverse imaging problems on the sphere
TLDR
This work describes a framework that leverages a proximal Markov chain Monte Carlo algorithm to efficiently sample the highdimensional space of spherical inverse problems with a sparsitypromoting wavelet prior and finds that it is potentially useful for a wide range of applications at moderate resolutions.
Scattering Networks on the Sphere for Scalable and Rotationally Equivariant Spherical CNNs
TLDR
This work develops scattering networks constructed natively on the sphere that provide a powerful representational space for spherical data and shows how they can be leveraged to scale spherical CNNs to the high resolution data typical of many practical applications.
Weak Lensing Trispectrum and Kurt-Spectra
We introduce two kurt-spectra to probe fourth-order statistics of weak lensing convergence maps. Using state-of-the-art numerical simulations, we study the shapes of these kurt-spectra as a function…
Weak-lensing mass reconstruction using sparsity and a Gaussian random field
TLDR
A novel approach to reconstructing dark matter mass maps from weak gravitational lensing measurements using an algorithm called MCALens based on an alternating minimisation incorporating both sparse recovery and proximal iterative Wiener filtering that exhibits improved estimation accuracy compared to customised mass-map reconstruction methods.
Cosmic shear cosmology beyond two-point statistics: a combined peak count and correlation function analysis of DES-Y1
We constrain cosmological parameters from a joint cosmic shear analysis of peak-counts and the two-point shear correlation function, as measured from the Dark Energy Survey (DES-Y1). We find the…
Higher-order statistics of shear field via a machine learning approach
TLDR
This work investigates the development of a new method to treat weak lensing higher order statistics, which are known to break degeneracy among cosmological parameters thanks to their capability of probing the non-Gaussian properties of the shear field.

Sparse Bayesian mass mapping with uncertainties: local credible intervals
TLDR
This work draws on the concept of local credible intervals as an extension of the uncertainty quantification techniques previously detailed, and finds that, typically, its recovered uncertainties are everywhere conservative, of similar magnitude and highly correlated with those recovered via Px-MALA.
