Example galaxies from the TNG50 simulation. Images are in projected stellar column density above 10⁴ M_⊙ kpc⁻² and represent a subset of Milky Way-like galaxies featuring prominent stellar streams, either linear or curved. The stellar masses of the galaxies are in the range log₁₀M_⋆/M_⊙ = 10.3 − 10.8, as indicated. Notice that two of the galaxies are repeated in different projections.
