Nuclear Rings in Simulated and Observed Galaxies: A Comparative Analysis between TNG-50 and SDSS-DR14.
In this study, we investigate the presence and properties of nuclear rings in the TNG-50 simulation and compare them with their observational counterparts from the SDSS-DR14 catalog. Nuclear rings are intriguing astronomical structures, the understanding of which provides valuable insights into galaxy formation and evolution.
Using data from the TNG-50 simulation, we identify and characterize a sample of nuclear rings in galaxies at different stages of their evolution. We analyze various properties to gain a better understanding of their dynamics and the physical processes that give rise to them. Subsequently, we conduct a comparative study with data from the SDSS-DR14 to verify whether the properties of nuclear rings in TNG-50 align with real observations. We evaluate their similarities and differences, highlighting the utility of cosmological simulations like TNG-50 in enhancing our understanding of these structures.
