Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application
Xinfeng Xu, Drummond Fielding, Timothy Heckman +12
Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…
The LBT Project II: MODS Spectra, Physical Conditions, and Oxygen Abundances in Local Metal-Poor Nebulae
Noah S. J. Rogers, Evan D. Skillman, Richard W. Pogge +7
Empirically measuring the primordial He mass fraction, , requires a significant number of low-metallicity nebulae with direct constraints on He/H and O/H abundances. Thi…
Resolving the Origins and Pathways of Ionizing Radiation Escape with UV Integral Field Spectroscopy
Cody Carr, Renyue Cen, Brian Fleming +4
The Epoch of Reionization marks the last major phase transition in the early Universe, during which the majority of neutral hydrogen once filling the intergalactic medium was ioniz…
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…
Evolution of the Ionizing Photon Luminosity Function
Stephan R. McCandliss, Swara Ravindranath, Sangeeta Malhotra +6
Counting the number and brightness of ionizing radiation sources out to a redshift of z ~ 1.2 will revolutionize our understanding of how the ionizing background is created and sus…
Spatially Resolving the Fundamental Elements of Reionization in Galaxies
Xinfeng Xu, Stephan McCandliss, Allison Strom +10
Cosmic reionization marks a critical epoch when the first galaxies ionized the intergalactic medium through the escape of Lyman continuum (LyC) radiation. Young, massive star clust…
