A spatially resolved view of Fast Radio Burst host metallicities with Integral-field Spectroscopy
Sunil Simha, Hsiao-Wen Chen, Wen-fai Fong +15
Magnetar sources are the leading theory for Fast Radio Burst (FRB) progenitors. If magnetars are indeed the dominant sources, we may thus expect any metallicity preference for magn…
