Radiative-transfer models of SN2023ixf require a 0.2 solar-mass cold dense shell plus rising dust mass to match its nebular-phase UV-optical-IR evolution to 1000 days.
Radiative-transfer models of SN2023ixf require prolonged CSM interaction and a cold dense shell to match its multi-wavelength photospheric evolution from 20 to 120 days.
A new two-parameter empirical magnitude-redshift relation for Type Ia supernovae fits observations comparably or better than LambdaCDM and indicates uniform cosmic acceleration.
SN 2020lao reached a specific kinetic energy of 5-7 x 10^51 erg per solar mass typical of engine-driven events yet showed no afterglow or excess emission, implying any jet was off-axis, choked, or absent.
