CHEFT: A Hybrid Effective Field Theory halo model
Marcos Pellejero Ibáñez, David Alonso, John A. Peacock +2
We present a hybrid halo model, which improves the description of the 2-halo term by incorporating non-linear information from simulations. A linear computation of the halo-halo po…
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…
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…
syren-halofit: A fast, interpretable, high-precision formula for the CDM nonlinear matter power spectrum
Deaglan J. Bartlett, Benjamin D. Wandelt, Matteo Zennaro +2
Rapid and accurate evaluation of the nonlinear matter power spectrum, , as a function of cosmological parameters and redshift is of fundamental importance in cosmology. Analy…
A precise symbolic emulator of the linear matter power spectrum
Deaglan J. Bartlett, Lukas Kammerer, Gabriel Kronberger +6
Computing the matter power spectrum, , as a function of cosmological parameters can be prohibitively slow in cosmological analyses, hence emulating this calculation is desira…
