MOSFIRE spectroscopy of galaxies in cosmic noon

This thesis make use of a recently commissioned spectrograph in one of the largest optical telescopes in the world to study galaxies that existed 10 billion years ago. The universe was only 3 billion years old at that time, and galaxies in that epoch were undergoing rapid evolution forming stars with high efficiency to form most of the present day observed matter. Using this data, we try to understand how galaxies like ours evolve from our old ancestors and how properties such as the mass of a galaxy and the environment in which it resides can affect the evolution.
