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…
Reconstructing spatially-varying multiplicative bias for Stage IV weak lensing galaxy surveys with a quadratic estimator
Konstantinos Tanidis, David Alonso, Lance Miller +1
We present a quadratic estimator that detects and reconstructs spatially-varying multiplicative () bias in weak lensing shear measurements, by exploiting the mode coupling…
Skew-spectra: a generalization to spin-
Alexander Roskill, Sara Maleubre, David Alonso +1
Skew-spectra allow us to extract non-Gaussian information by taking the square of a map and finding the power spectrum of this new map with the original map. This allows us to use…
Systematics mitigation for catalogue-based angular power spectra
Thomas Cornish, David Alonso, Boris Leistedt +1
Recent work has developed a formalism for computing angular power spectra directly from catalogues containing field values at discrete positions on the sky, thereby circumventing t…
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…
Low-redshift constraints on structure growth from CMB lensing tomography
Andrea Rubiola, Matteo Zennaro, Carlos García-García +2
We present constraints on the amplitude of matter fluctuations from the clustering of galaxies and their cross-correlation with the gravitational lensing convergence of the cosmic…
The impact of galaxy bias on cross-correlation tomography
Sara Maleubre, Matteo Zennaro, David Alonso +3
The cross-correlation of galaxies at different redshifts with other tracers of the large-scale structure can be used to reconstruct the cosmic mean of key physical quantities, and…
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…
Calibrating baryonic effects in cosmic shear with external data in the LSST era
Amy Wayland, David Alonso, Matteo Zennaro
Cosmological constraints derived from weak lensing (WL) surveys are limited by baryonic effects, which suppress the non-linear matter power spectrum on small scales. By combining W…
Robust cosmic shear with small-scale nulling
Giulia Piccirilli, Matteo Zennaro, Carlos García-García +1
Standard cosmological weak lensing analyses using cosmic shear are inevitably sensitive to small-scale, non-linear clustering from low-redshift structures. The need to adequately m…
