  This thesis explores the missing baryon problem in a computational context.
An overview of the problem is given, along with a discussion regarding the
relevance of the Circumgalactic Medium (CMG) and cosmological Zoom-in
simulations. The mechanisms underlying the N-body code ChaNGa (H. Menon, et
al., Computational Astrophysics and Cosmology 2, 1 (2015), arXiv:1409.1929), as
well as the data visualization and analysis tools yt (M. J. Turk, et al., 192,
9 (2011), arXiv:1011.3514) and trident (Hummels, et al., 847, 59 (2017),
arXiv:1612.03935) are presented at a conceptual level. Finally, a series of
synthetic quasar absorption spectra produced by using trident on a ChaNGa
dataset from (S. Roca-Fabrega, et al., 917, 64 (2021), arXiv:2106.09738) at
redshift of $z\sim4$ are shown. The low relative flux exhibited by these
spectra render absorption features indistinguishable from background noise, and
possible explanations for this phenomena such as high redshift are discussed.
Though the resulting spectra exhibit serious obstacles for both qualitative and
quantitative interpretation, they provide a "proof-of-concept" for future work,
demonstrating trident's compatibility with ChaNGa's data format. Future
prospects for using trident to analyze the CGM as simulated by ChaNGa are
discussed, as well as possible extensions of this project.
