AEOS: Star-by-Star Cosmological Simulations of Early Chemical Enrichment and Galaxy Formation
Kaley Brauer, Andrew Emerick, Jennifer Mead +7
The AEOS project introduces a series of high-resolution cosmological simulations that model star-by-star chemical enrichment and galaxy formation in the early Universe, achieving 1…
Code Comparison in Galaxy Scale Simulations with Resolved Supernova Feedback: Lagrangian vs. Eulerian Methods
Chia-Yu Hu, Matthew C. Smith, Romain Teyssier +8
We present a suite of high-resolution simulations of an isolated dwarf galaxy using four different hydrodynamical codes: {\sc Gizmo}, {\sc Arepo}, {\sc Gadget}, and {\sc Ramses}. A…
Spatially Resolved Gas-phase Metallicity in FIRE-2 Dwarfs: Late-Time Evolution of Metallicity Relations in Simulations with Feedback and Mergers
Lori E. Porter, Matthew E. Orr, Blakesley Burkhart +4
We present an analysis of spatially resolved gas-phase metallicity relations in five dwarf galaxies (, …
Characterizing the Circumgalactic Medium of the Lowest-Mass Galaxies: A Case Study of IC 1613
Yong Zheng, Andrew Emerick, Mary E. Putman +3
Using 10 sightlines observed with the Hubble Space Telescope/Cosmic Origins Spectrograph, we study the circumgalactic medium (CGM) and outflows of IC1613, which is a low-mass ($M_*…
Progenitor-mass-dependent yields amplify intrinsic scatter in dwarf-galaxy elemental abundance ratios
Dhruv A. Muley, Coral R. Wheeler, Philip F. Hopkins +3
In hydrodynamic simulations, prevailing subgrid chemical-evolution models often use a single, "IMF-averaged" supernova yield, ignoring variations in elemental abundance ratios (par…
The Role of Stellar Feedback in the Chemical Evolution of a Low Mass Dwarf Galaxy
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low
We investigate how each aspect of a multi-channel stellar feedback model drives the chemodynamical evolution of a low-mass, isolated dwarf galaxy using a suite of high-resolution s…
Exploring Chemical Homogeneity in Dwarf Galaxies: A VLT-MUSE study of JKB 18
Bethan L. James, Nimisha Kumari, Andrew Emerick +5
Deciphering the distribution of metals throughout galaxies is fundamental in our understanding of galaxy evolution. Nearby, low-metallicity, star-forming dwarf galaxies in particul…
Tentative Detection of the Circumgalactic Medium of the Isolated Low-Mass Dwarf Galaxy WLM
Y. Zheng, M. E. Putman, A. Emerick +7
We report a tentative detection of the circumgalactic medium (CGM) of WLM, an isolated, low-mass (log), dwarf irregular galaxy in the Local Group (LG). We an…
Simulating Metal Mixing of Both Common and Rare Enrichment Sources in a Low Mass Dwarf Galaxy
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low
One-zone models constructed to match observed stellar abundance patterns have been used extensively to constrain the sites of nucleosynthesis with sophisticated libraries of stella…
Stellar Radiation is Critical for Regulating Star Formation and Driving Outflows in Low Mass Dwarf Galaxies
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low
Effective stellar feedback is used in models of galaxy formation to drive realistic galaxy evolution. Models typically include energy injection from supernovae as the dominant form…
Metal Mixing and Ejection in Dwarf Galaxies is Dependent on Nucleosynthetic Source
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low +3
Using a high resolution simulation of an isolated dwarf galaxy, accounting for multi-channel stellar feedback and chemical evolution on a star-by-star basis, we investigate how eac…
Simulating an Isolated Dwarf Galaxy with Multi-Channel Feedback and Chemical Yields from Individual Stars
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low
In order to better understand the relationship between feedback and galactic chemical evolution, we have developed a new model for stellar feedback at grid resolutions of only a fe…
Grackle: a Chemistry and Cooling Library for Astrophysics
Britton D. Smith, Greg L. Bryan, Simon C. O. Glover +11
We present the Grackle chemistry and cooling library for astrophysical simulations and models. Grackle provides a treatment of non-equilibrium primordial chemistry and cooling for…
Gas Loss by Ram Pressure Stripping and Internal Feedback From Low Mass Milky Way Satellites
Andrew Emerick, Mordecai-Mark Mac Low, Jana Grcevich +1
The evolution of dwarf satellites of the Milky Way is affected by the combination of ram pressure and tidal stripping, and internal feedback from massive stars. We investigate gas…
Warm Gas in and Around Simulated Galaxy Clusters as Probed by Absorption Lines
Andrew Emerick, Greg Bryan, Mary E. Putman
Understanding gas flows into and out of the most massive dark matter structures in our Universe, galaxy clusters, is fundamental to understanding their evolution. Gas in clusters i…
In-Medium Quarkonia at SPS, RHIC and LHC
