CoLoRe-2LPT: Lyman- mock catalogues for the validation of DESI cosmological analyses
M. F. Ruiz-Herrera Bernal, S. Avila, A. Font-Ribera +90
The paper presents fast Lyman‑α forest mock catalogues generated with second‑order Lagrangian perturbation theory (2LPT) that accurately reproduce small‑scale clustering, BAO broad…
Analytical covariances for catalogue-based pseudo-s
Kevin Wolz, Elyas Farah, Robert Reischke +2
The paper presents a method to analytically compute the Gaussian (disconnected) covariance of angular power spectra estimated directly from discrete source catalogues, accounting f…
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…
Low-redshift constraints on structure growth from CMB lensing tomography
Andrea Rubiola, Matteo Zennaro, Carlos GarcÃa-GarcÃa +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…
Probing baryonic feedback with fast radio bursts: joint analyses with cosmic shear and galaxy clustering
Amy Wayland, David Alonso, Robert Reischke
Cosmological inference from weak lensing (WL) surveys is increasingly limited by uncertainties in baryonic physics, which suppress the non-linear matter power spectrum on small sca…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
