Magnetar Engines in Broad-lined Type Ic Supernovae and a Unified Picture for Magnetar-powered Stripped-envelope Supernovae
Jin-Ping Zhu, Bing Zhang
We model the multi-band lightcurves of 80 SNe Ic-BL, including 11 associated with lGRBs, using a magnetar engine model with Ni decay. We find that the data are all consisten…

EP250108a/SN2025kg: A Magnetar-powered Gamma-Ray Burst Supernova Originating from a Close Helium-star Binary via Isolated Binary Evolution
Jin-Ping Zhu, Jian-He Zheng, Bing Zhang
SN\,2025kg, linked to EP250108a, is among the brightest broad-lined Type Ic supernova (SN Ic-BL) known, showing unique helium absorptions, a late-time broad H, and an early bum…

EP240414a: Off-axis View of a Jet-Cocoon System from an Expanded Progenitor Star
Jian-He Zheng, Jin-Ping Zhu, Wenbin Lu +1
When a relativistic jet is launched following the core-collapse of a star, its interaction with the stellar envelope leads to the formation of a hot cocoon, which produces various…
