A guide to choosing data compression methods for cosmological inference
Susan Pyne, Benjamin Joachimi, Calum Gordon +1
We provide a pedagogical guide to help researchers choose an appropriate compression method for cosmological inference and numerical covariance estimation, trading off the balance…
Third-order intrinsic alignment of SDSS BOSS LOWZ galaxies
Laila Linke, Susan Pyne, Benjamin Joachimi +4
Cosmic shear is a powerful probe of cosmology, but it is affected by the intrinsic alignment (IA) of galaxy shapes with the large-scale structure. Upcoming surveys like Euclid and…
Three-point intrinsic alignments of dark matter halos in the IllustrisTNG simulation
Susan Pyne, Ananth Tenneti, Benjamin Joachimi
We use the IllustrisTNG suite of cosmological simulations to measure intrinsic alignment (IA) bispectra of dark matter subhalos between redshifts 0 and 1. We decompose the intrinsi…
Self-calibration of weak lensing systematic effects using combined two- and three-point statistics
Susan Pyne, Benjamin Joachimi
We investigate the prospects for using the weak lensing bispectrum alongside the power spectrum to control systematic uncertainties in a Euclid-like survey. Three systematic effect…
Weak lensing deflection of three-point correlation functions
Susan Pyne, Benjamin Joachimi, Hiranya V. Peiris
Weak gravitational lensing alters the apparent separations between observed sources, potentially affecting clustering statistics. We derive a general expression for the lensing def…
