Electron densities and filling factors of extragalactic HII regions: NGC 2403 and NGC 628
Almudena Zurita, Fabio Bresolin, Estrella Florido +3
Measurements of the electron density of populations of extragalactic HII regions in nearby galaxies remain limited, despite the relevance of this quantity for characterizing the po…
Consistent Gas-Phase Temperatures and Metallicities from UV and Optical Nebular Emission: A Reliable Foundation from z=0 to Cosmic Dawn
Erin Huntzinger, Yuguang Chen, Tucker Jones +6
The rest-frame UV spectra of star-forming galaxies are increasingly important as they become one of the primary windows to probe the physical properties of cosmic dawn (z>8) galaxi…
Consistent gas-phase C/O abundances from UV and optical emission lines: a robust scale for chemical evolution across cosmic time
Paige M. Kelly, Tucker Jones, Yuguang Chen +5
The carbon to oxygen (C/O) abundance ratio is a valuable tracer of star formation history, as C and O enrichment occurs on different timescales. However, measurements based on ultr…
SIGNALS on the mixing of oxygen and nitrogen in the spiral galaxy NGC 6946
Fabio Bresolin, David Fernández-Arenas, Laurie Rousseau-Nepton +10
As part of the SIGNALS survey, which comprises a sample of approximately 40 nearby galaxies observed with the Fourier transform spectrometer SITELLE, we present a study of metal mi…
Joint Optical and Infrared Observations of N and O Reveal the Dust-Obscured Gas in Haro 3
Yuguang Chen, Tucker Jones, Ryan L. Sanders +22
Accurate chemical compositions of star-forming regions are a critical diagnostic tool to characterize the star formation history and gas flows which regulate galaxy formation. Howe…
The Trace of the CNO Cycle in the Ring Nebula NGC6888
A. Mesa-Delgado, C. Esteban, J. García-Rojas +3
We present new results on the chemical composition of the Galactic ring nebula NGC6888 surrounding the WN6(h) star WR136. The data are based on deep spectroscopical observations ta…
The Unique Na:O Abundance Distribution in NGC 6791: The First Open(?) Cluster with Multiple Populations
D. Geisler, S. Villanova, G. Carraro +4
Almost all globular clusters investigated exhibit a spread in their light element abundances, the most studied being a Na:O anticorrelation. In contrast, open clusters show a homog…
