Coevolution of Bar and Spiral Arms in TNG50 Simulations Using Information Theory

The Astrophysical Journal
Using Information Theory, we investigate the coevolution of bars and spiral arms in barred-spiral galaxies from the cosmological magnetohydrodynamic Illustris TNG50 simulations. We first calculate Mutual Information (MI) between a structural or kinematic

. As a result of our statistical study of 540 edgeon galaxies, we present here the images and preliminary statistical analysis of a sub-sample of 60 galaxies, that were selected to be S-type warped spirals.
