Deep Learning Calibration of the Quasar X-ray/UV Luminosity Relation for Cosmological Applications
Jiaze Gao, Yun Chen, Lixin Xu +2
Quasars can serve as standard candles through an empirical scaling relation between their ultraviolet (UV) and X-ray luminosities. As high-redshift probes, it is critical to test w…

Redshift Evolution of the HII Galaxy - Relation: Gaussian Process Analysis and Cosmological Implications
Jiaze Gao, Yun Chen, Lixin Xu
The empirical correlation between the H luminosity () and the ionized gas velocity dispersion () in HII starburst galaxies (HIIGs) provides a foundation for using them as…
