Large Dark Matter Content and Steep Metallicity Profile Predicted for Ultradiffuse Galaxies Formed in High-spin Halos
We study the stellar properties of a sample of simulated ultradiffuse galaxies (UDGs) with stellar mass M _⋆ = 10 ^7.5 –10 ^9 M _⊙ , selected from the TNG50 simulation, where UDGs form mainly in high-spin dwarf-mass halos. We divide our sample into star-forming and quenched UDGs, finding good agreem...
