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…

Detailed theoretical modelling of the kinetic Sunyaev-Zel'dovich stacking power spectrum
Amy Wayland, David Alonso, Adrien La Posta
We examine, from first principles, the angular power spectrum between the kinematic Sunyaev-Zel'dovich effect (kSZ) and the reconstructed galaxy momentum - the basis of existing an…

: insights on gas thermodynamics from the combination of X-ray and thermal Sunyaev-Zel'dovich data cross-correlated with cosmic shear
Adrien La Posta, David Alonso, Nora Elisa Chisari +2
We measure the cross-correlation between cosmic shear from the third-year release of the Dark Energy Survey, thermal Sunyaev-Zel'dovich (tSZ) maps from Planck, and X-ray maps from…
