Effects of galactic environment on size and dark matter content in low-mass galaxies
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,200 galaxies (886 ce...

We conclude that a galaxy’s relative size is set by the combined effects from it’s environment and halo mass.

We conclude that a galaxy’s relative size is set by the combined effects from it’s environment and halo mass.
Using a Random Forest regression model, we find that while galactic environment is significant in predicting a galaxy’s relative size, it’s halo mass plays a similarly important role.

Using a Random Forest regression model, we find that while galactic environment is significant in predicting a galaxy’s relative size, it’s halo mass plays a similarly important role.
Specifically, we look into how environment predicts deviations away from 3 key galaxy scaling relationships at fixed stellar mass.
