A visual census of the TNG50 simulation finds 807 ringed galaxies (59% inner rings), which are redder, more metal-rich, and less star-forming than matched non-ringed galaxies, with inner rings at the half-mass radius and outer rings at 1.5 times it.

abstract
Galaxy morphology is a product of how galaxies formed, how they interacted with their environment, how they were influenced by internal perturbations, AGN, and dark matter, and of their varied star formation histories. This article reviews the phenomenology of galaxy morphology and classification with a view to delineating as many types as possible and how they relate to physical interpretations. The old classification systems are refined, and new types introduced, as the explosion in available morphological data has modified our views on the structure and evolution of galaxies.

A catalog of ringed galaxies in the TNG50 simulation: Analysis of their properties and structure
A visual census of the TNG50 simulation finds 807 ringed galaxies (59% inner rings), which are redder, more metal-rich, and less star-forming than matched non-ringed galaxies, with inner rings at the half-mass radius and outer rings at 1.5 times it.
