Ultra-Violet Luminosity Functions and The Mass-Metallicity Relation

Abstract

In recent years, high-resolution and highly sensitive telescopes and detectors have emerged, allowing researchers to more accurately measure the ultraviolet luminosity function of dust attenuation, thereby constraining cosmological parameters such as galaxy density, evolution speed, and cosmic geometry. Therefore, the research topic of this article is the relationship between ultra-violet luminosity function (UV-LF) and the mass metal relationship. The research method of this article is as follows: Firstly, consider Stellar population synthesis, Lyman- α Absorption, Dust attention, and Lyman Break selection analyzed one of the models of UV-LF, and based on this, study the relationship between UV-LF and the mass metal relationship. Research has found that generally speaking, galaxies or celestial bodies with higher metallicity may experience more significant attenuation of ultraviolet light due to the presence of more dust particles. On the contrary, galaxies or celestial bodies with lower metal abundance may have relatively small ultraviolet luminosity attenuation due to their lower dust content. It should be noted that this correlation is not a simple linear relationship, but is influenced by multiple complex factors.
