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…

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…
