    Simulating High-redshift Galaxies: Enhancing UV Luminosity with Star Formation Efficiency and a Top-heavy IMF by Tae Bong Jeong, Myoungwon Jeon, Hyunmi Song, Volker Bromm

    Published 2025-01-01
    “…Recent findings from photometric and spectroscopic JWST surveys have identified examples of high-redshift galaxies at z  ≳ 10. These high- z galaxies appear to form much earlier and exhibit greater UV luminosity than predicted by theoretical work. …”
