Self-Consistent Modified Gravity Catalogues

Background: The simulation methodology adopted uses a generative model based on a GR-based catalogue to predict the gravitational redshift signal, which can introduce discrepancies if modified gravity affects the halo population itself.

Question / Future Work: It is crucial to develop and utilize halo catalogues in modified gravity that are populated self-consistently with member galaxies, rather than relying on GR-based catalogues, to accurately reflect potential deviations from GR.
