The Emergence of Bulges and Disks in the Universe.

Fundamentally, galaxies consist of different components with different physics. The two most significant components could be considered as disk and bulge. Having different studies at the local Universe, we know that the dynamic, star formation, kinematic and stellar population in these two components are different. So the question is what physical processes and evolutionary history have leaded galaxy components to the shape we observe today? By structural decomposition of galaxies over a high dynamic range in both redshift and stellar mass, I investigate how the most resolved imaging data from the Hubble Space Telescope in COSMOS/DEVILS field can help us to disentangle galaxies into their components and study the evolution of mass and size of the components. This will tell us how the components of galaxies assemble their mass and how they relate to their size. Such a mass and size exploration of the components of galaxies might reveal how/why we see a heterogeneous population of galaxies having at least two very disparate ingredients
