Constraints on the r-process Delay Time from Dwarf Spheroidal Galaxies
Lauren E. Henderson, Evan N. Kirby, Mithi A. C. de los Reyes +1
The ancient stellar populations and simple structure of the local dwarf spheroidal galaxies (dSphs) make them excellent laboratories for studying the chemical evolution of the earl…
KBSS-InCLOSE II: First Detailed Insights on the Inner CGM of Low-Mass Galaxies
Evan Haze Nunez-Cravin, Charles C. Steidel, Gwen C. Rudie +7
We present results from an extension to the Keck Baryonic Structure Survey (KBSS) that focuses on the Inner Circumgalactic Medium (CGM) of QSO Line Of Sight Emitting galaxies at z$…
The Treasury of Extremely Metal-Poor O Stars
O. Grace Telford, Christiana Erba, Kristen B. W. McQuinn +10
The Treasury of Extremely Metal-Poor O Stars (TEMPOS) is a Hubble Space Telescope survey of hot and massive O-type stars in nearby, low-metallicity galaxies (20% of the s…
It's a matter of time: Empirical Constraints on Supernova Yields and Delay Times from Dwarf Spheroidal Galaxies
Mairéad E. Heiger, Alexander P. Ji, Joshua S. Speagle +6
The chemical abundances of a stellar population encode information about nucleosynthesis and its astrophysical sites, but this information is confounded by the specific star format…
A Spectroscopic Survey of Metal-Poor OB Stars in Local Dwarf Galaxy NGC 3109
Abby Mintz, O. Grace Telford, Evan N. Kirby +3
As JWST uncovers increasingly strong evidence that metal-poor, massive stars in early galaxies dominated reionization, observational constraints on the properties of such stars are…
An analytical galactic chemical evolution model with gas inflow and a terminal wind
Kateryna A. Kvasova, Evan N. Kirby
We present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram…
Neutron-capture Element Abundances of 491 Stars in Milky Way Dwarf Satellite Galaxies from Medium-Resolution Spectra
Lauren E. Henderson, Evan N. Kirby, Mithi A. C. de los Reyes +2
The chemical compositions of evolved stars in Local Group dwarf spheroidal galaxies (dSphs) provide insight into the galaxy's past star formation and nucleosynthesis. Neutron-captu…
The Hubble Space Telescope Survey of M31 Satellite Galaxies IV. Survey Overview and Lifetime Star Formation Histories
A. Savino, D. R. Weisz, A. E. Dolphin +35
From orbits of HST imaging, we present deep homogeneous resolved star color-magnitude diagrams that reach the oldest main sequence turnoff and uniformly measured star forma…
KBSS-InCLOSE I: Design and First Results from the Inner CGM of QSO Line Of Sight Emitting Galaxies at z~2-3
Evan Haze Nunez, Charles C. Steidel, Evan N. Kirby +10
We present the design and first results of the Inner Circumgalactic Medium (CGM) of QSO Line of Sight Emitting galaxies at , KBSS-InCLOSE. The survey will connect galaxy…
Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-Poor Star KIC 8144907
Daniel Huber, Ditte Slumstrup, Marc Hon +15
Very metal-poor stars ([Fe/H]<-2) are important laboratories for testing stellar models and reconstructing the formation history of our galaxy. Asteroseismology is a powerful tool…
Metals in Star-Forming Galaxies with KCWI. I. Methodology and First Results on the Abundances of Iron, Magnesium, and Oxygen
Zhuyun Zhuang, Evan N. Kirby, Charles C. Steidel +6
Understanding the chemical enrichment of different elements is crucial to gaining a complete picture of galaxy chemical evolution. In this study, we present a new sample of 46 low-…
