Luke Davies colloquium: Star formation, Mergers and the Assembly of Stellar Mass in Galaxies
Since the first stars and then galaxies formed the Universe has been an immense factory converting neutral gas into stellar material. The distribution of this stellar material is key to our understanding of galaxy formation and evolution as it is the primary baryonic component we can observe in galaxies over the last 13Gyr. However, the changing distribution of stars at a given epoch is dependant on many different processes such as: i) in-situ star-formation rates, ii) merger rates, iii) the neutral gas reservoirs available for future star-formation episodes, iv) the effect of galaxy-galaxy interactions on both star-formation and neutral gas content and v) AGN activity. These processes occur in different measures to all galaxies over the history of the Universe, ultimately resulting in the distribution of stellar material we see today. If we wish to understand the assembly of stellar mass in the Universe we must aim to probe all of these process, and build a complete and consistent picture of their interplay over cosmic timescales.
