Late-time radio observations of SN 2012au show re-brightening best explained by emission from a newborn pulsar wind nebula rather than continued shock interaction with circumstellar material.

A new radiative-diffusion framework couples magnetar spin-down, shock propagation, and radiative transport to produce double-peaked, merged, or single-peaked light curves in engine-powered transients, demonstrated on LSQ14bdq.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
Broad-lined Type Ic supernovae are powered by magnetar engines, showing a universal ejecta-mass versus initial-spin correlation across stripped-envelope supernova types that supports a common progenitor framework.
