Central densities of dark matter halos in FIRE-2 simulations of low-mass galaxies with cold dark matter and self-interacting dark matter
Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock +6
We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Fe…
Shapes of Milky-Way-Mass Galaxies with Self-Interacting Dark Matter
Drona Vargya, Robyn Sanderson, Omid Sameie +4
Self-interacting dark matter (SIDM) models offer one way to reconcile inconsistencies between observations and predictions from collisionless cold dark matter (CDM) models on dwarf…
The central densities of Milky Way-mass galaxies in cold and self-interacting dark matter models
Omid Sameie, Michael Boylan-Kolchin, Robyn Sanderson +6
We present a suite of baryonic cosmological zoom-in simulations of self-interacting dark matter (SIDM) haloes within the ``Feedback In Realistic Environment'' (FIRE) project. The t…
A Relationship Between Stellar Metallicity Gradients and Galaxy Age in Dwarf Galaxies
Francisco J. Mercado, James S. Bullock, Michael Boylan-Kolchin +7
We explore the origin of stellar metallicity gradients in simulated and observed dwarf galaxies. We use FIRE-2 cosmological baryonic zoom-in simulations of 26 isolated galaxies as…
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…
