A dark matter profile to model diverse feedback-induced core sizes of CDM haloes
Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +11
We analyze the cold dark matter density profiles of 54 galaxy halos simulated with FIRE-2 galaxy formation physics, each resolved within of the halo virial radius. These ha…

Stars made in outflows may populate the stellar halo of the Milky Way
Sijie Yu, James S. Bullock, Andrew Wetzel +8
We study stellar-halo formation using six Milky Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that of the outer ( kpc) stellar halo in each sy…
