Joint tomographic measurement of thermal Sunyaev Zeldovich and the cosmic infrared background
Adrien La Posta, David Alonso, Carlos García-García +1
We present a novel method for the tomographic reconstruction of the bias-weighted mean electron pressure and star formation rate density $\langle bρ_{\mathrm…

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…

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…
