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…
The Simulated Oxygen Shortage (SOS): Mapping the Missing OVI in Simulated Dwarf Galaxies to Subgrid Physics
Daniel R. Piacitelli, Alyson M. Brooks, N. Nicole Sanchez +9
Observations reveal extended \OVI\, reservoirs in the circumgalactic medium (CGM) of dwarf galaxies, yet current simulations systematically underpredict \OVI\, column densities. Ut…
Trends with Mass for Dwarf Galaxies from the Marvelous Massive Dwarfs Suite
Dilys Ruan, Alyson M. Brooks, Leonardo A. Barba +7
Galaxy formation scenarios can be interpreted through galaxy morphology and the level of rotational versus pressure support, quantified through the ratio of a galaxy's rotation spe…
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…
Optimized smoothing kernels for SPH
Robert Wissing, Thomas R. Quinn, Ben Keller +2
We present a set of new smoothing kernels for smoothed particle hydrodynamics (SPH) that improve the convergence of the method without any additional computational cost. These kern…
