Peak absolute magnitude of KNe from binary configurations consistent with the chirp mass of GW190425. Left, central, and right panels: respectively, the g (484 nm), r (626 nm), and J (1250 nm) bands. Orange and blue lines refer to the EoSs APR4 and DD2, respectively. Solid and dot-dashed lines refer to a BH spin of 0.99 and 0, respectively. Dotted vertical lines indicate the maximum NS mass for the two EoSs.
