On priors and scale cuts in EFT-based full-shape analyses
Anton Chudaykin, Mikhail M. Ivanov, Takahiro Nishimichi
Parameter estimation from galaxy survey data from the full-shape method depends on scale cuts and priors on EFT parameters. The effects of priors, including the so-called ''prior v…

High-redshift Millennium and Astrid galaxies in effective field theory at the field level
James M. Sullivan, Carolina Cuesta-Lazaro, Mikhail M. Ivanov +6
Effective Field Theory (EFT) modeling is expected to be a useful tool in the era of future higher-redshift galaxy surveys such as DESI-II and Spec-S5 due to its robust description…

Lyman Alpha Forest - Halo Cross-Correlations in Effective Field Theory
Anton Chudaykin, Mikhail M. Ivanov
We provide a perturbative effective field theory (EFT) description for anisotropic (redshift-space) correlations between the Lyman alpha forest and a generic biased tracer of matte…
