Intense CIV and HeII Emission in z~0 Galaxies: Probing High-Energy Ionizing Photons
Danielle A. Berg, John Chisholm, Dawn K. Erb +3
In the last few years, prominent high-ionization nebular emission lines (i.e., OIII], CIII], CIV, HeII) have been observed in the deep UV spectra of z~5-7 galaxies, indicating that…
The production and escape of ionizing photons from galaxies over cosmic time (Astro2020 Science White Paper)
Jane R. Rigby, Danielle Berg, Rongmon Bordoloi +10
The ionizing photons produced by massive stars are key actors in galaxy evolution. Ionizing photon production and escape is poorly understood. Improved space-based, spatially-resol…
Astro2020 Science White Paper: Radial Metallicity Gradients in Star-Forming Galaxies
Letizia Stanghellini, Danielle Berg, Fabio Bresolin +2
Spiral star-forming galaxies are complex astrophysical objects whose baryonic component is dominated by the disk, where most of the star formation resides. The metallicity in the d…
Accurate Distances to Important Spiral Galaxies: M63, M74, NGC 1291, NGC 4559, NGC 4625, NGC 5398
Kristen B. W. McQuinn, Evan D. Skillman, Andrew E. Dolphin +2
Accurate distances are fundamental to interpreting many measured properties of galaxies. Surprisingly, many of the best-studied spiral galaxies in the Local Volume have distance un…
ALFALFA Discovery of the Most Metal-Poor Gas-Rich Galaxy Known: AGC 198691
Alec S. Hirschauer, John J. Salzer, Evan D. Skillman +12
We present spectroscopic observations of the nearby dwarf galaxy AGC 198691. This object is part of the Survey of HI in Extremely Low-Mass Dwarfs (SHIELD) project, which is a multi…
