Abstract

Galaxies come in different shapes, sizes, ages, and compositions. Our study's goal is to audit a certain group of hydrogen-rich galaxies to determine their metal content, also known as metallicity. Each galaxy we look at has a different amount and makeup of metals that makeup its interstellar medium. This medium is made mostly of hydrogen and helium with traces of other elements. Our results showed that galaxies have a wide range of different compositions. Recording this information sheds light onto how our universe evolved over time and may lead to further studies down the road.
