Complete fifth-order galaxy bias renormalization in real space enables consistent two-loop power spectrum and one-loop bispectrum/trispectrum calculations for biased tracers with operator-level counterterms.
First GI BAO measurement from DES Y3 photometric data yields α = 0.966 ± 0.252, consistent with density BAO α = 0.966 ± 0.037 at 0.86σ detection.
The parity-odd intrinsic alignment power spectrum probes the collapsed limit of the parity-odd primordial trispectrum and can tighten constraints on parity-violating PNG when bias parameters are calibrated from N-body simulations.
