Dust in galaxy evolution and SED modelling

How galaxies evolve into the form they are observed today is one of the biggest questions in astrophysics. We get the information about galaxies across history from their emission across the electromagnetic spectrum, known as spectral energy distribution (SED), at different timescales. This thesis focuses on dust's roles in galaxies, including how it shapes the emission profile. This is the first work that simulates dust physics in galaxy evolution self-consistently and predicts the galaxy emission across the panchromatic spectrum. This thesis provides a foundation for future surveys and theoretical models that includes dust to understand galaxy formation.
