BayeSN analysis of ZTF Type Ia supernovae confirms a ~0.1 mag intrinsic environmental step in standardized brightness that is not explained by differences in dust extinction properties.
A robust statistical test for galaxy catalog magnitude completeness improves H0 constraints by 1.3-8.6% in GWTC-1 analyses but shows no benefit for GWTC-3 due to limited K-band coverage in GLADE+.

Implementing a Robust Test of Galaxy Catalogue Completeness for Dark Siren Measurements of the Hubble Constant
A robust statistical test for galaxy catalog magnitude completeness improves H0 constraints by 1.3-8.6% in GWTC-1 analyses but shows no benefit for GWTC-3 due to limited K-band coverage in GLADE+.
