Euclid preparation. LII. Forecast impact of super-sample covariance on 3x2pt analysis with Euclid
Euclid Collaboration, D. Sciotti, S. Gouyou Beauchamps +221
Deviations from Gaussianity in the distribution of the fields probed by large-scale structure surveys generate additional terms in the data covariance matrix, increasing the uncert…
LimberJack.jl: auto-differentiable methods for angular power spectra analyses
J. Ruiz-Zapatero, D. Alonso, C. García-García +5
We present LimberJack.jl, a fully auto-differentiable code for cosmological analyses of 2 point auto- and cross-correlation measurements from galaxy clustering, CMB lensing and wea…
Optimal constraints on Primordial non-Gaussianity with the eBOSS DR16 quasars in Fourier space
Marina S. Cagliari, Emanuele Castorina, Marco Bonici +1
We present constraints on the amplitude of local Primordial Non-Gaussianities (PNG), , using the quasar sample in the Sloan Digital Sky Survey IV extended Baryon Oscill…
Capse.jl: efficient and auto-differentiable CMB power spectra emulation
Marco Bonici, Federico Bianchini, Jaime Ruiz-Zapatero
We present Capse.jl, a novel neural network-based emulator designed for rapid and accurate prediction of Cosmic Microwave Background (CMB) temperature, polarization, and lensing an…
