Weighted Webs: Morphology-Informed Marked Fields
Mikel Martin Barandiaran, Jessica A. Cowell, David Alonso +2
The paper investigates how weighting the cosmic matter density field by morphological characteristics of the cosmic web (such as filamentarity and tidal shear) can enhance constrai…
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…
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…
