Other Abstract

Galaxies are the cornerstones of large cosmological structures, their formation and evolution are one of the frontier subjects in the 21 century astrophysics. Nearby galaxies are close to us and can be observed with great details, thus they can provide us with the most abundant observables that can be used to constrain various theoretical models.Therefore,they are ideal“laboratories”to study the formation,structure,and evolution history of galaxies. In order to understand the evolution history of galaxies in general, it is essential to start with individual galaxies. The phenomenological model has been proven to be a powerful tool to explore the formation and evolution of individual disk galaxies.In this work, we use the phenomenological model to study an isolated low-mass disk galaxy NGC300 and a relatively complicated interacting high-mass disk galaxy M51a. Based on the best-fitting model predictions of NGC300 and M51a,a study is made to compare the results with that of their counter-parts in our previous work.Then we could have a better understanding of the formation and evolution of disk galaxies.
