Non-linear Evolution of Dark Plasma Subhalos
Andrew Liu, Anirudh Prabhu, Akaxia Cruz +1
The paper uses particle-in-cell simulations to study how electrostatic plasma instabilities in dark-matter subhalos orbiting the Milky Way grow non‑linearly, causing turbulent heat…
MARVELously Dark: the density profile evolution of dwarf halos in velocity-dependent SIDM
Anna Engelhardt, Ferah Munshi, Annika H. G. Peter +6
Self-interacting dark matter (SIDM) with a sufficiently large cross section has been shown to naturally produce constant dark matter (DM) cores, as well as core-collapse, at the ce…
Probing the Nature of Dark Matter Self-Interactions Through Observations of Massive Black Hole Mergers
Zachary J. Hoelscher, Kelly Holley-Bockelmann, Akaxia Cruz +1
Though the nature of dark matter remains elusive, two models have come to prominence with testable predictions: cold dark matter (CDM) and self-interacting dark matter (SIDM). Whil…
Structure Formation with Dark Magnetohydrodynamics
Pierce Giffin, Andrew Liu, Jeremias Boucsein +4
Long-range interactions in the dark sector can give rise to collective plasma phenomena that are capable of modifying the evolution of dark matter halos. We present the first study…
Marvelous Metals: Surveying the Circumgalactic Medium of Simulated Dwarf Galaxies
Daniel R. Piacitelli, Alyson M. Brooks, Charlotte Christensen +7
Dwarf galaxies are uniquely sensitive to energetic feedback processes and are known to experience substantial mass and metal loss from their disk. Here, we investigate the circumga…
Dwarf diversity in CDM with baryons
Akaxia Cruz, Alyson Brooks, Mariangela Lisanti +7
Observed rotation curves of dwarf galaxies exhibit significant diversity at fixed halo mass, challenging galaxy formation within the Cold Dark Matter (CDM) model. Previous cosmolog…
