Description
Composed of sheets, walls, and filaments, the cosmic web connects clusters of galaxies together and is responsible for regulating galaxy evolution by the accreting mass into galaxies via filaments [3]. In an effort to further understand the evolution of galaxies, we first study filaments and devise an interactive analytical model for disk galaxies with accurate inflow and outflow rates of matter. Using accretion rates and feedback rates from different regions in the Galaxy, it is now possible to model and predict galactic behavior for a galaxy with similar mass and morphology as the Milky Way. Other models simulate feedback or accretion processes numerically and in greater detail. Here we consolidate the rates to make one single model for the galaxy as a whole. In this model, we take the rates from other papers and use them to calculate the total mass flowed, energy used, distance travelled, and current location of the gas from the following parameters: change in time, redshift value, morphology of the galaxy, and type of active galactic nuclei (AGN) the galaxy has at its center. Although, we have just begun to make this detailed model, it will serve as the foundation for future work to be done to further understand galaxy evolution.
