Sub-kiloparsec Imaging of Lyman-alpha Emission in a Low Mass, Highly Ionized, Gravitationally Lensed Galaxy at z = 1.84
Dawn K. Erb, Danielle A. Berg, Matthew W. Auger +3
Low mass, low metallicity galaxies at low to moderate () redshifts offer the best opportunity for detailed examination of the interplay between massive stars, ionizing…
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…
Constraining the metallicities, ages, star formation histories, and ionizing continua of extragalactic massive star populations
J. Chisholm, J. R. Rigby, M. Bayliss +4
We infer the properties of massive star populations using the far-ultraviolet stellar continua of 61 star-forming galaxies: 42 at low-z observed with HST and 19 at z~2 from the Meg…
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…
Mapping Gas Phase Abundances and Enrichment Patterns Across Galaxy Disks
Kathryn Kreckel, Danielle Berg, Guillermo A. Blanc +12
The distribution of gas-phase abundances in galaxy disks encodes the history of nucleosynthesis and transport through the interstellar medium (ISM) over cosmic time. Multi-object a…
