Abstract
We request 4 hours using GMOS-N IFU to study the detailed kinematics and composition of the inner region of PGC 045903, a galaxy with a large central structure that calls into question our understanding of the dynamical evolution of bars and nuclear disks. The Fast Turnaround Gemini observations will allow us to identify the formation mechanism of large nuclear disks observed in some barred galaxies.
