Abstract

This study examines the physical properties and correlations for dwarf galaxies, including irregular (dIrr) and elliptical (dE) types. Data from the NASA/IPAC and HyperLEDA databases were used to analyze relationships among parameters such as distance to galaxy, absolute magnitude of galaxy, mass of galaxy, and surface brightness of galaxy using regression analysis. Results show strong negative correlations between absolute magnitude and mass of galaxy, and strong positive correlations between mass of galaxy and both redshift of galaxy and surface brightness. A moderate positive relationship between dIrr and dE types in terms of galaxy mass and brightness is also observed. These findings enhance our understanding of dwarf galaxy formation and evolution.
