Spectroscopic observations of six low-mass, metal-poor SLSN host galaxies reveal slow stellar-wind-driven outflows with velocities 37-104 km/s and mass-loading factors below 1 in the earliest phases of star formation.
A coupled magnetar–CSM hybrid model produces diverse SLSN light curves by letting the magnetar-driven shock overtake and dominate circumstellar interaction.
Fitting 80 SNe Ic-BL lightcurves with a magnetar-plus-Ni model reveals a universal ejecta-mass–spin-period anti-correlation linking SNe Ic-BL, SLSNe, and FBOTs to a common magnetar origin.
slicersim is a modular Python tool that simulates IFS observations including noise and instrumental effects, demonstrating that the Lazuli Space Observatory could observe 8000 SNe Ia (z=0–1.5) at S/N=25 per resolution element in 1.5 years of on-sky time.
SLSN 2021bnw is best fit by a core-collapse explosion of a star with initial mass at least 61 solar masses, ejecta of 15-22.5 solar masses containing 1.7 solar masses of nickel-56 and 4 foe energy colliding with 7 solar masses of circumstellar matter.
SKA+VLBI will enable routine mas-scale imaging of nearby extragalactic supernovae to measure shock deceleration and test explosion mechanisms.
