A Luminous Precursor in the Extremely Bright GRB 230307A
GRB 230307A is an extremely bright long-duration GRB with an observed gamma-ray fluence of ≳3 × 10 ^−3 erg cm ^−2 (10–1000 keV), second only to GRB 221009A. Despite its long duration, it is possibly associated with a kilonova, thus resembling the case of GRB 211211A. In analogy with GRB 211211A, we...
