Interacting galaxies in the IllustrisTNG simulations -- VI: Reconstructed orbits, close encounters and mergers
David R. Patton, Lawrence Faria, Maan H. Hani +4
Cosmological simulations have been used to study interacting galaxies as a function of galaxy pair separation, enabling comparisons with observational studies of galaxy pairs. The…

Interacting galaxies in the IllustrisTNG simulations -- VII: The connection between the most luminous active galactic nuclei and galaxy interactions
Shoshannah Byrne-Mamahit, David R. Patton, Sara L. Ellison +5
We investigate the connection between the most luminous active galactic nuclei (AGN), galaxy pairs, and post-mergers in the IllustrisTNG simulation. We select galaxy pairs and post…

The limitations (and potential) of non-parametric morphology statistics for post-merger identification
Scott Wilkinson, Sara L. Ellison, Connor Bottrell +4
Non-parametric morphology statistics have been used for decades to classify galaxies into morphological types and identify mergers in an automated way. In this work, we assess how…
