Density reconstruction from biased tracers: Testing the equivalence principle through consistency relations
Lawrence Dam, Omar Darwish
The paper introduces a quadratic‑estimator method that uses the anti‑symmetric modulation of cross‑power spectra between different biased tracers to test the weak equivalence princ…

Gravitational redshift from large-scale structure: nonlinearities, antisymmetries, and the dipole
Lawrence Dam, Camille Bonvin
Gravitational redshift imprints a slight asymmetry in the observed clustering of galaxies, producing odd multipoles (e.g. the dipole) in the cross-correlation function. But there a…

Euclid: Relativistic effects in the dipole of the 2-point correlation function
F. Lepori, S. Schulz, I. Tutusaus +130
Gravitational redshift and Doppler effects give rise to an antisymmetric component of the galaxy correlation function when cross-correlating two galaxy populations or two different…
