Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model
Lucie Scharré, Michaela Hirschmann, Adèle Plat +10
Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extre…

RUBIES: The Evolution of the Ionization Parameter from 0 < z < 9
Nikko J. Cleri, Zach J. Lewis, Joel Leja +10
The dimensionless ionization parameter, U=q/c, where q is the ratio of the local ionizing photon flux to the local hydrogen density, is a key metric to parameterize nebular conditi…

Euclid: The Early Release Observations Lens Search Experiment
J. A. Acevedo Barroso, C. M. O'Riordan, B. Clément +206
We investigated the ability of the Euclid telescope to detect galaxy-scale gravitational lenses. To do so, we performed a systematic visual inspection of the Eucl…
