The cosmological analysis of DES 32pt data from the Effective Field Theory of Large-Scale Structure
Guido D'Amico, Alexandre Refregier, Leonardo Senatore +1
We analyze the Dark Energy Survey (DES) Year 3 data using predictions from the Effective Field Theory of Large-Scale Structure (EFTofLSS). Specifically, we fit three two-point obse…

Neutrino masses from large-scale structures: future sensitivity and theory dependence
Davide Racco, Pierre Zhang, Henry Zheng
In the incoming years, cosmological surveys aim at measuring the sum of neutrino masses , complementing the determination of their mass ordering from laboratory experiments…
