Characterizing the Average Interstellar Medium Conditions of Galaxies at z\sim 5.6-9 with UV and Optical Nebular Lines

Ultraviolet (UV; rest-frame \sim1200-2000 A) spectra provide a wealth of diagnostics to characterize fundamental galaxy properties, such as their chemical enrichment, the nature of their stellar populations, and their amount of Lyman-continuum (LyC) radiation. In this work, we leverage publicly released JWST data to construct the rest-frame UV-to-optical composite spectrum... Show more
