Star formation and chemical compositions in nearby galaxies 

The visible matter in galaxies is constantly cycling between two distinct phases: gas and stars. This "baryon cycle" can help us learn about how galaxies form and evolve. In this talk, I will show how we can use nearby galaxies to study this cycle. For example, the processes in the baryon cycle can be traced by different galaxy properties, like mass, metallicity, and star formation. I will discuss some of the relationships between these properties, and what these can tell us about galaxy evolution. I will also describe how we can use our understanding of the baryon cycle to address other astrophysical questions, such as the dominant physical channel of Type Ia supernova explosions. Throughout the talk, I will discuss my own development as a researcher starting as an undergraduate student.
