JWST data reconstructs the inner ejecta of SNR 0540-69.3 as two similar-sized fragmented lobes, implying a ~300 km/s pulsar kick under symmetry assumption and confirming low-velocity hydrogen mixing in a Type II explosion.

The authors implement and validate nuclear networks coupled to GRRMHD with M1 neutrino transport in Gmunu, showing effects on core-collapse supernova shock revival and composition.
A balloon mission concept with 8192 TES detectors projects 200 eV FWHM resolution at 511 keV and 35-sigma detection of the galactic center 511 keV line to study its shape and substructure.
SN 2025coe's double-peaked light curve and nebular spectra are consistent with either an asymmetric core-collapse explosion of a low-mass He-core progenitor or a thermonuclear hybrid white dwarf merger.
Asymmetric neutrino emissions produce proton-rich ejecta in one hemisphere and neutron-rich ejecta in the other, with asymmetries of 30% or more overproducing elements heavier than zinc relative to solar abundances.
