Stellar streams record the accretion history of their host galaxy. We present a set of simulated streams from disrupted dwarf galaxies in 13 cosmological simulations of Milky Way (MW)–mass galaxies from the FIRE-2 suite at z = 0, including seven isolated MW-mass systems and six hosts resembling the MW–M31 pair. In total, we identify 106 simulated stellar streams, with no significant differences in the number of streams and the masses of their progenitors between the isolated and paired…
