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.
JWST TRGB distances to 10 SN Ia hosts update calibrations for 11 SNe yielding H0 of 68.4-69.6 km/s/Mpc and show modest shifts when combined with prior HST data.
Baby-universe absorption model accounts for late-time acceleration and yields w(z) < -1 without a cosmological constant.
A review of late-universe models concludes that DESI BAO plus uncalibrated supernovae data indicate the Hubble tension originates in new low-redshift physics.
