What mechanism is proposed to explain the extreme luminosity of Super-Luminous Supernovae like ASASSN-15lh?

Answer

The presence of a magnetar

The mechanism proposed involves a rapidly spinning neutron star with an immense magnetic field (a magnetar) dumping rotational energy into the expanding supernova ejecta, significantly boosting the visible output.
