Probing the origin of the kilonova candidate GRB 230307A: analysis of host galaxy and offset
Clecio R. Bom, Davi C. Rodrigues, Arianna Cortesi +12
We investigate the host galaxy of the long gamma-ray burst GRB 230307A, which is associated with a kilonova candidate likely produced by a binary neutron-star (BNS) merger. The tra…
