Charting the expansion of the Universe from z0 to z14 with HII galaxies

R. Chávez, R. Terlevich, A. L. González-Morán +14

We present an updated Hubble diagram of giant extragalactic H II regions and H II galaxies spanning the redshift interval to , extending the use of the $L(\math…

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…

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.…

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…

Mapping the Hubble Flow from z0 to z7.5 with HII Galaxies

Ricardo Chávez, Roberto Terlevich, Elena Terlevich +7

Over twenty years ago, Type Ia Supernovae (SNIa) observations revealed an accelerating Universe expansion, suggesting a significant dark energy presence, often modelled as a cosmol…

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…

Alternative High-z Cosmic Tracers and the Dark Energy Equation of State

M. Plionis, R. Terlevich, S. Basilakos +4

We propose to use alternative cosmic tracers to measure the dark energy equation of state and the matter content of the Universe [w(z) & Ω_m]. Our proposed method consists of two c…
