Theoretical strong line metallicity diagnostics for the JWST era
Prerak Garg, Desika Narayanan, Ryan L. Sanders +5
The ratios of strong rest-frame optical emission lines are the dominant indicator of metallicities in high-redshift galaxies. Since typical strong-line based metallicity indicators…
Gauging the mass of metals in the gas phase of galaxies from the Local Universe to the Epoch of Reionization
K. E. Heintz, A. E. Shapley, R. L. Sanders +10
The chemical enrichment of dust and metals are vital processes in constraining the star formation history of the universe. Previously, the dust masses of high-redshift star-forming…
Unravelling the Dust Attenuation Scaling Relations and their Evolution
Gabriel Maheson, Roberto Maiolino, Mirko Curti +3
We explore the dependence of dust attenuation, as traced by the Balmer decrement, on galactic properties by using a large sample of SDSS spectra. We use both Part…
The MOSDEF-LRIS Survey: Detection of Inflowing Gas Towards Three Star-forming Galaxies at z ~ 2
Andrew Weldon, Naveen A. Reddy, Michael W. Topping +9
We report on the discovery of cool gas inflows towards three star-forming galaxies at 2.30. Analysis of Keck Low-Resolution Imaging Spectrometer spectroscopy r…
Ultra-deep Keck/MOSFIRE spectroscopic observations of galaxies: direct oxygen abundances and nebular excitation properties
Leonardo Clarke, Alice Shapley, Ryan L. Sanders +6
Using deep near-infrared Keck/MOSFIRE observations, we analyze the rest-optical spectra of eight star-forming galaxies in the COSMOS and GOODS-N fields. We reach integration times…
Accurate Oxygen Abundance of Interstellar Gas in Mrk 71 from Optical and Infrared Spectra
Yuguang Chen, Tucker Jones, Ryan Sanders +9
The heavy element content ("metallicity") of the Universe is a record of the total star formation history. Gas-phase metallicity in galaxies, as well as its evolution with time, is…
An Updated Dust-to-Star Geometry: Dust Attenuation Does Not Depend on Inclination in Star-Forming Galaxies from MOSDEF
Brian Lorenz, Mariska Kriek, Alice E. Shapley +10
We investigate dust attenuation and its dependence on viewing angle for 308 star-forming galaxies at from the MOSFIRE Deep Evolution Field (MOSDEF) survey. We di…
A JWST/NIRSpec Exploration of the Connection between Ionization Parameter, Electron Density, and Star-Formation-Rate Surface Density in z=2.7-6.3 Galaxies
Naveen A. Reddy, Michael W. Topping, Ryan L. Sanders +2
We conduct a statistical analysis of the factors responsible for the variation in the ionization parameter (U) of high-redshift star-forming galaxies based on medium resolution JWS…
Direct T_e-based Metallicities of z=2-9 Galaxies with JWST/NIRSpec: Empirical Metallicity Calibrations Applicable from Reionization to Cosmic Noon
Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +2
We report detections of the [OIII]4364 auroral emission line for 16 galaxies at z=2.1-8.7, measured from JWST/NIRSpec observations obtained as part of the Cosmic Evolution Early…
JWST/NIRSpec Measurements of the Relationships Between Nebular Emission-line Ratios and Stellar Mass at z~3-6
Alice E. Shapley, Naveen A. Reddy, Ryan L. Sanders +2
We analyze the rest-optical emission-line ratios of star-forming galaxies at 2.7<=z<6.5 drawn from the Cosmic Evolution Early Release Science (CEERS) Survey, and their relationship…
The Impact of Star-Formation-Rate Surface Density on the Electron Density and Ionization Parameter of High-Redshift Galaxies
Naveen A. Reddy, Ryan L. Sanders, Alice E. Shapley +6
We use the large spectroscopic dataset of the MOSFIRE Deep Evolution Field (MOSDEF) survey to investigate some of the key factors responsible for the elevated ionization parameters…

Excitation and Ionization Properties of Star-forming Galaxies at z=2.0-9.3 with JWST/NIRSpec
Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +2
We utilize medium-resolution JWST/NIRSpec observations of 164 galaxies at from the Cosmic Evolution Early Release Science (CEERS) survey to investigate the evolution of…
Early Results from GLASS-JWST. XXI: Rapid assembly of a galaxy at z=6.23 revealed by its C/O abundance
Tucker Jones, Ryan Sanders, Yuguang Chen +21
The abundance of carbon relative to oxygen (C/O) is a promising probe of star formation history in the early universe, as the ratio changes with time due to production of these ele…
