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…
Recommendations for the Astronomy Graduate Admissions Process
Emily M. Levesque, Courtney D. Dressing, Rachel Ivie +4
As the AAS Working Group on Graduate Admissions (WGGA) we are sharing brief recommendations for improving and standardizing key elements of the graduate admissions process in astro…
AAS Graduate Admissions Task Force: Final report and recommendations
Emily M. Levesque, Rachel Ivie, Christopher Johns-Krull +7
In March of 2024 the AAS formed our Graduate Admissions Task Force (GATF), asking us to produce recommendations aimed at improving the state of graduate admissions in astronomy. Th…
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 signatures of density fluctuations and mixing gas in circumgalactic absorption systems
Yakov Faerman, Daniel R. Piacitelli, Matthew McQuinn +1
We investigate the prospects for detecting and constraining density and temperature inhomogeneities in the circumgalactic medium (CGM) using absorption measurements of metal ions.…
Absorption-based Circumgalactic Medium Line Emission Estimates
Daniel R. Piacitelli, Erik Solhaug, Yakov Faerman +1
Motivated by integral field units (IFUs) on large ground telescopes and proposals for ultraviolet-sensitive space telescopes to probe circumgalactic medium (CGM) emission, we surve…
The Impact of Cosmic Rays on the Kinematics of the Circumgalactic Medium
Iryna S. Butsky, Jessica K. Werk, Kirill Tchernyshyov +9
We use hydrodynamical simulations of two Milky Way-mass galaxies to demonstrate the impact of cosmic-ray pressure on the kinematics of cool and warm circumgalactic gas. Consistent…
