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-…
Reimagining SED Fitting with Cosmological Galaxy Simulations and Machine Learning
Dhruv T. Zimmerman, Desika Narayanan
SED fitting is the most common technique to recover galaxy physical properties from observed photometry. However, SED fitting requires many assumptions that essentially collapse a…
Dust in the Average Galaxy: Attenuation, Emission, and Opacity from
Caitlin M. Casey, Hollis B. Akins, Andrew J. Battisti +43
We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…
The AURORA Survey: Multiple Balmer and Paschen Emission Lines for Individual Star-forming Galaxies at z=1.5-4.4. II. Implications for Nebular Dust Corrections, Nebular SFRs, and Differential Reddening
Naveen A. Reddy, Alice E. Shapley, Ryan L. Sanders +10
We discuss the implications of the nebular dust attenuation curves derived for 24 galaxies at z=1.5-4.4 with multiple detections of HI Balmer and Paschen recombination emission lin…
Molecular Gas Excitation in z ~ 0.7 Gas-Rich Post-starburst Galaxies from SQuIGGLE
Vincenzo R. D'Onofrio, Justin S. Spilker, Rachel Bezanson +10
Many post-starburst galaxies at have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may…
The AURORA Survey: Tracing Galactic Outflows at with JWST/NIRSpec NUV Absorption Lines
Emily Kehoe, Alice E. Shapley, Ryan L. Sanders +13
We probe galactic-scale outflows in star-forming galaxies at drawn from the \textit{JWST}/NIRSpec AURORA program. For the first time, we directly compare outflow prop…
