The assembly history of NGC 1365 through chemical archaeology
Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8
Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…
The abundance and emission of PAHs from the local to early Universe
Massimiliano Parente, Desika Narayanan, Paul Torrey +8
We present the first large-volume cosmological simulation of galaxy evolution with a model for the abundance and luminous emission of Polycyclic Aromatic Hydrocarbons (PAHs) across…
The lifetimes and properties of Little Red Dots in the AMBRA simulation
Patrick LaChance, Yihao Zhou, Aklant Kumar Bhowmick +6
We identify and analyze the little red dots (LRDs) in the AMBRA cosmological hydrodynamic simulation, by producing mock observations of the galaxies and active galactic nuclei (AGN…
The Mass Dependence of the Fundamental Metallicity Relation in Observations and Simulations
Laura Carnevale, Alex M. Garcia, Paul Torrey +8
The metal content of galaxies provides direct insight into the underlying physical processes that drive galaxy evolution. An example of this is the three-parameter relationship bet…
Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +8
The JWST discoveries of supermassive black holes (BHs) at may provide key insights into their seeding origins. Using new BRAHMA cosmological sim…
Learning the Universe at High Redshifts: Impact of Accretion Modeling on Early Black Hole Growth
Jonathan Kho, Aklant K. Bhowmick, Rainer Weinberger +8
JWST discoveries of the earliest () supermassive black holes (BHs, ) challenge the BH seeding and accretion models of most cosmol…
First results of AMBRA: Abundant Seeds and Early Mergers as a Pathway to the First Massive Black Holes
Yihao Zhou, Aklant Kumar Bhowmick, Tiziana Di Matteo +6
AMBRA combines the large cosmological volume and statistical power of ASTRID with the physically motivated gas-based black hole seeding models from BRAHMA. Motivated by JWST's disc…
How Mergers and Flybys Shape Azimuthal Age Patterns in Spiral Galaxies
Qian-Hui Chen, Alex M. Garcia, Zefeng Li +7
Spiral structures are one of the most common features in galaxies, yet their origins and evolution remain debated. Stellar age distributions offer crucial insights into galaxy evol…
The AURORA Survey: The Mass -- Metallicity and Fundamental Metallicity Relations at Based Purely on Direct Metallicities
Ali Ahmad Khostovan, Ryan L. Sanders, Alice E. Shapley +14
We present new constraints on the Mass -- Metallicity (MZR) and Fundamental Metallicity Relations (FMR) using a sample of 34 galaxies at (median ). The…
The abundance and properties of the lowest luminosity dwarf galaxies around the Milky Way: Insights from Semi-Analytic Models
Niusha Ahvazi, Andrew B. Pace, Christopher T. Garling +11
We investigate the formation and observable properties of faint satellite galaxies (M$_\rm V > -3$) in Milky Way-like halos using the semi-analytic galaxy formation model Galacticu…
Environmental vs. intrinsic quenching at cosmic noon: Predictions from cosmological hydrodynamical simulations for VLT-MOONRISE
Paul H. Goubert, Asa F. L. Bluck, Joanna M. Piotrowska +5
We present an investigation into the quenching of simulated galaxies across cosmic time, honing in on the role played by both intrinsic and environmental mechanisms at different ep…
Polycyclic Aromatic Hydrocarbons (PAHs) in the High-redshift Universe: Prospect of the PRIMA FIRESS low-resolution spectroscopy
Ilsang Yoon, Brandon Hensley, Thomas S. -Y. Lai +6
The integrated luminosity from the features of the polycyclic aromatic hydrocarbons (PAHs) exceeds the luminosity from atomic and molecular emission lines in the star-forming regio…
A Uniform Analysis of Gas-phase Metallicity Evolution with 1-3 Gyr Time Sampling over the Past 12 Billion Years
Shweta Jain, Ryan L. Sanders, Ali Ahmad Khostovan +6
We present a systematic investigation of the evolution of the mass-metallicity relation (MZR) and fundamental metallicity relation (FMR) using uniform metallicity diagnostics acros…
A Physically Motivated Framework to Compare Merger Timescales of Isolated Low- and High-Mass Galaxy Pairs Across Cosmic Time
Katie Chamberlain, Ekta Patel, Gurtina Besla +2
The merger timescales of isolated low-mass pairs () on cosmologically motivated orbits have not yet been studied in detail, though isolated hig…
Dust Survival in Galactic Winds
Helena M. Richie, Evan E. Schneider, Matthew W. Abruzzo +1
We present a suite of high-resolution numerical simulations to study the evolution and survival of dust in hot galactic winds. We implement a novel dust framework in the Cholla hyd…
