Abstract

To understand the universe around us we must first know and understand its components. Our current understanding of the matter-energy composition of the universe is that it is about 5% baryonic (everyday) matter, 68% dark energy, and about 27% dark matter. However, as of yet, we remain unsure how to define dark matter and understand its behavior. This research program focused on a hypothetical particle candidate for dark matter, the axion. This proposed dark matter evolves into unique physical structures, which we call solitons. Solitons may be described as a general area of center mass, a core, rather than a point. Our research will focus on the difference between axion-like fuzzy dark matter (FDM) and a more traditional dark matter paradigm, cold dark matter (CDM). We have used a publicly-available gravitational lensing code, deeplenstronomy, to simulate gravitational lensing data collected by the Vera C. Rubin Observatory's upcoming Legacy Survey of Space and Time (LSST). Within this paper, we will examine how this gravitational lensing differs from that of cold dark matter, and how the resulting data compares to the data which will be found with the LSST, and what this clarifies.
