What is Multi-Messenger Tests for Fast-Spinning Newborn Pulsars Embedded in Stripped-Envelope Supernovae about?

Fast-spinning strongly magnetized newborn neutron stars, including nascent magnetars, are popularly implemented as the engine of luminous stellar explosions. Here, we consider the scenario that they power various stripped-envelope supernovae, not only super-luminous supernovae Ic but also broad-line supernovae Ibc and possibly some ordinary supernovae Ibc. This scenario is also motivated by the hypothesis that Galactic magnetars largely originate from fast-spinning neutron stars as remnants of stripped-envelope supernovae. By consistently modeling the energy injection from magnetized wind and Ni decay, we show that proto-neutron stars with >~ 10 ms rotation and B_dip >~ 5 x 10^14 G can be harbored in ordinary supernovae Ibc. On the other hand, millisecond proto-neuton stars can solely power broad-line supernovae Ibc if they are born with poloidal magnetic field of B_dip >~ 5 x 10^14 G, and superluminous supernovae Ic with B_dip >~ 10^13 G. Then, we study how multi-messenger emission can be used to discriminate such pulsar-driven supernova models from other competitive scenarios. First, high-energy x-ray and gamma-ray emission from embryonic pulsar wind nebulae is a promising smokin
