Orientations of DM Halos in FIRE-2 Milky Way-mass Galaxies
Jay Baptista, Robyn Sanderson, Dan Huber +11
The shape and orientation of dark matter (DM) halos are sensitive to the micro-physics of the DM particle, yet in many mass models, the symmetry axes of the Milky Way's DM halo are…
Comparing Implementations of Self-Interacting Dark Matter in the Gizmo and Arepo Codes
Helen Meskhidze, Francisco J. Mercado, Omid Sameie +4
Self-interacting dark matter (SIDM) models have received great attention over the past decade as solutions to the small-scale puzzles of astrophysics. Though there are different im…
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…
Simulating the "hidden giant" in cold and self-interacting dark matter models
Omid Sameie, Sukanya Chakrabarti, Hai-Bo Yu +4
We perform a series of controlled N-body simulations to study realizations of the recently discovered Antlia 2 galaxy in cold dark matter (CDM) and self-interacting dark matter (SI…
Self-Interacting Dark Matter Subhalos in the Milky Way's Tides
Omid Sameie, Hai-Bo Yu, Laura V. Sales +2
We study evolution of self-interacting dark matter (SIDM) subhalos in the Milky Way (MW) tidal field. The interaction between the subhalos and the MW's tides lead to more diverse d…
Globular Clusters Formed within Dark Halos I: present-day abundance, distribution and kinematics
Peter Creasey, Laura V. Sales, Eric W. Peng +1
We explore a scenario where metal poor globular clusters (GCs) form at the centres of their own dark matter halos in the early universe before reionization. This hypothesis leads t…
