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…
The Seven Dwarfs illuminated. The impact of radiation on dwarf galaxies and their circumgalactic medium
Bernhard Baumschlager, Sijing Shen, James W. Wadsley +6
We present a high-resolution cosmological zoom-in simulation of a group of field dwarf galaxies which includes on-the-fly radiative transfer (RT) and is evolved to . Emission…
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…
Predictions for Detecting a Turndown in the Baryonic Tully Fisher Relation
Dilys Ruan, Alyson M. Brooks, Akaxia Cruz +5
The baryonic Tully Fisher relation (bTFR) provides an empirical connection between baryonic mass and dynamical mass (measured by the maximum rotation velocity) for galaxies. Due to…
