kSZ for everyone: the pseudo-Cl approach to stacking
Lea Harscouet, Kevin Wolz, Amy Wayland +2
We present a harmonic-space estimator for the cross-correlation between the kinematic Sunyaev-Zel'dovich effect and the reconstructed galaxy momentum field that offers several prac…
Cosmological constraints from the angular power spectrum and bispectrum of luminous red galaxies and CMB lensing
Francesco Verdiani, Lea Harscouet, Matteo Zennaro +2
We study the projected clustering of photometric luminous red galaxies from the DESI Legacy Survey, combining their angular power spectrum, bispectrum, and cross-correlation with m…
Constraints from CMB lensing tomography with projected bispectra
Lea Harscouet, David Alonso, Andrina Nicola +1
We measure the angular power spectrum and bispectrum of the projected overdensity of photometric DESI luminous red galaxies, and its cross-correlation with maps of the Cosmic Micro…
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…
