Recovering Ionizing Photon Escape and Galaxy Scaling Relations in the LzLCS via Si II and C II Absorption Lines and Mock Spectra from a Radiation-Hydrodynamic Simulation

John Trevino, Simon Gazagnes, Danielle A. Berg +7

In this work, we use a radiation-hydrodynamic simulation of a single virtual galaxy to study Si II and C II line profiles seen in stacked HST/COS spectra of 58…

The Evolution of Low-Ionization Electron Densities in Galaxies Across Cosmic Epochs

Mabel G. Stephenson, John Chisholm, Alberto Saldana-Lopez +12

We investigate the low-ionization electron density in the interstellar medium of galaxies across , derived with the [O II] and [S II]$λ\lambda6718…

Nitrogen abundances in star-forming galaxies 2.2 Gyr after the Big Bang are not elevated

D. Schaerer, Y. I. Izotov, R. Marques-Chaves +22

Using deep medium-resolution JWST rest-optical spectra of a sample of typical star-forming galaxies (Lyman break galaxies and Lyman- emitters) from the LyC22 survey at $z \sim 3…

Lyman Continuum escaping from in-situ formed stars in a tidal bridge at z = 3

T. E. Rivera-Thorsen, A. Le Reste, M. J. Hayes +11

We present an analysis of archival JWST NIRSpec IFS and HST imaging observations of the z = 3 Lyman-Continuum Emitter (LCE) candidate LACES104037. We show that a nearby galaxy, den…

Finding He II: Testing Novel Models of Binary Populations across Cosmic Time

Beryl Hovis-Afflerbach, Allison L. Strom, Alberto Saldana-Lopez +1

Our understanding of massive stars remains incomplete. Many high-z galaxies and nearby analogs exhibit strong He II emission, indicating an abundance of photons with energies >54.4…

CLASSY XIII. Cutting through the Clouds - Comparing Indirect Tracers of Ionizing Photon Escape

Kaelee S. Parker, Danielle A. Berg, John Chisholm +25

The Epoch of Reionization (EoR) provides critical insights into the role of early galaxies in shaping the ionization state of the universe. However, because of the opacity of the i…
