Abstract

We present a systematic investigation aimed at probing potential associations between historic local Universe core-collapse supernovae (CCSNe) and fast radio bursts (FRBs). Motivated by the growing evidence that young magnetars may power at least a subset of FRBs, we cross-match a sample of Type II and Ib/c CCSNe within 200\,Mpc, observable with the CHIME telescope, against the FRB events reported in CHIME/FRB Catalog-1. Our analysis employs rigorous selection criteria based on spatial coincidence, dispersion measure, and scattering constraints to identify candidate associations that could directly test the young magnetar progenitor model. Although our search yields a candidate match, the probability of a chance alignment remains high, precluding a definitive association at this stage. Nonetheless, the study demonstrates the viability of this cross-matching approach and underscores the need for dedicated follow-up observations of promising candidates to search for persistent or transient radio activity indicative of a young magnetar. This work lays the groundwork for future observational efforts aimed at elucidating the connection between the explosive endpoints of massive stars and the enigmatic FRB phenomenon.
