First Co-spatial Comparison of Stellar, Neutral-, and Ionized-gas Metallicities in a metal-rich galaxy: M83
Svea Hernandez, Alessandra Aloisi, Bethan L. James +14
We carry out a comparative analysis of the metallicities from the stellar, neutral-gas, and ionized-gas components in the metal-rich spiral galaxy M83. We analyze spectroscopic obs…
Improving Helium Abundance Determinations with Leo P as a Case Study
Erik Aver, Danielle A. Berg, Keith A. Olive +3
Currently, the primordial helium abundance is best estimated through spectroscopic observations of H II regions in metal-poor galaxies. However these determinations are limited by…
CHAOS V: Recombination Line Carbon Abundances in M101
Evan D. Skillman, Danielle A. Berg, Richard W. Pogge +3
The CHAOS project is building a large database of LBT H II region spectra in nearby spiral galaxies to use direct abundances to better determine the dispersion in metallicity as a…
A comparison of UV and optical metallicities in star-forming galaxies
Nell Byler, Lisa J Kewley, Jane R Rigby +5
Our ability to study the properties of the interstellar medium (ISM) in the earliest galaxies will rely on emission line diagnostics at rest-frame ultraviolet (UV) wavelengths. In…
The Leoncino Dwarf Galaxy: Exploring the Low-Metallicity End of the Luminosity-Metallicity and Mass-Metallcity Relations
Kristen. B. W. McQuinn, Danielle A. Berg, Evan D. Skillman +10
Extremely metal-poor (XMP) galaxies are low-mass, star-forming galaxies with gas-phase oxygen abundances below 12+log(O/H) = 7.35 (~1/20 Zsun). Galaxy evolution scenarios suggest t…
CHAOS IV: Gas-Phase Abundance Trends From The First Four CHAOS Galaxies
Danielle A. Berg, Richard W. Pogge, Evan D. Skillman +4
The chemical abundances of spiral galaxies, as probed by HII regions across their disks, are key to understanding the evolution of galaxies over a wide range of environments. We pr…
