Weighted Webs: Morphology-Informed Marked Fields
Mikel Martin Barandiaran, Jessica A. Cowell, David Alonso +2
The morphology of the cosmic web formed by the late-time matter distribution encodes cosmological information beyond that contained in standard two-point statistics. Marked power s…
First Constraints from Marked Angular Power Spectra with Subaru Hyper Suprime-Cam Survey First-Year Data
Jessica A. Cowell, Joaquin Armijo, Leander Thiele +7
We present the first application of marked angular power spectra to weak lensing data, using maps from the Subaru Hyper Suprime-Cam Year 1 (HSC-Y1) survey. Marked convergence field…
Hitting the mark: Optimising Marked Power Spectra for Cosmology
Jessica A. Cowell, David Alonso, Jia Liu
Marked power spectra provide a computationally efficient way to extract non-Gaussian information from the matter density field using the usual analysis tools developed for the powe…
Fast Projected Bispectra: the filter-square approach
Lea Harscouet, Jessica A. Cowell, Julia Ereza +4
The study of third-order statistics in large-scale structure analyses has been hampered by the increased complexity of bispectrum estimators (compared to power spectra), the large…
