An Optical Illusion: High Electron Densities Create Extremely Metal-Poor Galaxy Impostors

Tiger Yu-Yang Hsiao, Danielle A. Berg, Steven L. Finkelstein +8

JWST has enabled the discovery of dozens of extremely metal-poor galaxies (EMPGs) with metallicities below , representing a significant leap toward detecting the fi…

Hunting Wandering 3<z<8 Black Holes: Spatial Offsets in Ionization Ratio and Continuum Emission

Urvi Thakurdesai, Anthony J. Taylor, Steven L. Finkelstein +14

The early growth and assembly of supermassive black holes (SMBHs) remain key topics of interest in galaxy evolution. One of the scenarios predicted by theoretical models is that fr…
