Direct Tests of Black Hole Accretion Rate Prescriptions: I. Bondi Accretion at Different Scales
James Agostino, Ming-Yi Lin, Natasha Jones +9
We present spatially resolved parsec-scale measurements of nuclear conditions (gas density and kinetic temperature) relevant for black hole accretion rate predictions in the Seyfer…
The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations
Desika Narayanan, Paul Torrey, Massimiliano Parente +16
We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…
The Entangling of Supernova Feedback Impacts with Coarsening Simulation Resolution
Eric Zhang, Laura V. Sales, Thales A. Gutcke +11
It is often understood that supernova (SN) feedback in galaxies is responsible for regulating star formation (SF) and generating gaseous outflows. However, a detailed look at their…
Probing the Hot Gaseous Halos of Milky Way-like Galaxies in the TNG50 simulation
Zhijie Zhang, Xiaoxia Zhang, Taotao Fang +9
The origin and structure of the hot (K) gaseous halo around Milky Way (MW)-mass galaxies provide a critical test for galaxy formation models. We perform a comprehensi…
Dust and Grain Size Evolution in Galaxy Simulations: What Matters and What Does Not
Massimiliano Parente, Desika Narayanan, Paul Torrey
We present the first implementation of an evolving dust grain size distribution (GSD) within a semi-analytic cosmological model (SAM) of galaxy evolution. This flexible model self-…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles
Alex M. Garcia, Jonah C. Rose, Paul Torrey +23
In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…
