Conference Talk

Speaker

Mikhail Ivanov

Description

I will overview recent advances in modeling of the high-redshift tracers, such as the Lyman-alpha forest, Lyman-alpha emitting galaxies, and Lyman-break galaxies at the field level using large-scale structure effective field theory. I will then discuss various new opportunities that this modeling offers, including generation of high-quality mock catalogs and simulation-based priors for analyses of DESI-II and Spec-S5 data.
