Charting the expansion of the Universe from z0 to z14 with HII galaxies
R. Chávez, R. Terlevich, A. L. González-Morán +14
The authors construct an updated Hubble diagram using 243 giant H II regions and H II galaxies from redshift 0 to ~14, applying the L(Hβ)–σ relation to derive cosmological paramete…
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…
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…
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…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
