Joint photometric cross-calibration and SED modeling in BayeSN yields G26 model with 12% NMAD scatter reduction on DES-SN5YR supernovae at z<0.7.
Global 3D hydrodynamical simulations show that a turbulence-driven deflagration-to-detonation transition produces nearly identical peak spectra across diverse ignition densities and topologies in near-Chandrasekhar white dwarfs, matching SN 1999aa.
Progenitor age is the primary physical driver of the host-mass and host-sSFR magnitude steps in Type Ia supernovae, with the mass step eliminated by direct age correction.
Large sample of SN Ia hosts shows young mean progenitor age of 3.5 Gyr and only 1.5 Gyr evolution, leading to negligible cosmological bias of 0.007 mag.
Full-GR simulations find that inhomogeneous curvature produces only sub-dominant systematic offsets in growth-rate measurements from magnitude fluctuations at z ≲ 0.2 relative to current statistical errors.
The progenitor-age bias correction for SN Ia cosmology is robust to host-progenitor age mapping uncertainties from different delay-time distributions, leaving the redshift-dependent magnitude correction and cosmological impact largely unchanged.
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.
Using ZTF DR2 data, AGN presence in Type Ia supernova host galaxies at z<0.15 shows no significant systematic effect on Hubble residuals.
Lazuli is proposed as a space observatory combining flagship sensitivity with response times one to two orders of magnitude faster than current large facilities to enable new time-domain and multi-messenger science.
