Sparse Bayesian mass-mapping using trans-dimensional MCMC
Augustin Marignier, Thomas Kitching, Jason D. McEwen +1
Uncertainty quantification is a crucial step of cosmological mass-mapping that is often ignored. Suggested methods are typically only approximate or make strong assumptions of Gaus…
A New Estimator for Phase Statistics
D. Munshi, R. Takahashi, J. D. McEwen +2
We introduce a novel statistic to probe the statistics of phases of Fourier modes in two-dimensions (2D) for weak lensing convergence field . This statistic contains completely…
Posterior sampling for inverse imaging problems on the sphere in seismology and cosmology
Augustin Marignier, Jason D. McEwen, Ana M. G. Ferreira +1
Inverse problems defined on the sphere arise in many fields, including seismology and cosmology where problems are defined on the globe and the cosmic sphere. These are generally h…
Position-Dependent Correlation Function of Weak Lensing Convergence
D. Munshi, G. Jung, T. D. Kitching +4
We provide a systematic study of the position-dependent correlation function in weak lensing convergence maps and its relation to the squeezed limit of the three-point correlation…
Morphology of Weak Lensing Convergence Maps
D. Munshi, T. Namikawa, J. D. McEwen +2
We study the morphology of convergence maps by perturbatively reconstructing their Minkowski Functionals (MFs). We present a systematics study using a set of three generalised skew…
Weak Lensing Skew-Spectrum
D. Munshi, T. Namikawa, T. D. Kitching +2
We introduce the skew-spectrum statistic for weak lensing convergence maps and test it against state-of-the-art high-resolution all-sky numerical simulations. We perform the an…
