Bars and spiral arms are among the most prominent dynamical features shaping the evolution of disk galaxies. Their formation, persistence, and secular influence on galactic structure and star formation remain central topics in modern astrophysics. Over the past decades, both observational and theoretical advances — from high-resolution spectroscopy and integral field surveys of nearby galaxies to cosmological simulations resolving early disk formation — have revealed that bars and spirals are not transient phenomena, but dynamically coupled structures that evolve over cosmic time.
This two-day Greek–Italian workshop aims to bring together researchers working on the dynamics and evolution of disk galaxies, combining expertise from orbital theory, N-body/hydrodynamic simulations, and multi-wavelength observations. The meeting will focus on the dynamical mechanisms underlying bar and spiral formation, the role of resonances and pattern speeds, and the connection between local galaxies and their high-redshift progenitors.
By fostering discussion between groups in Athens and Padova — as well as collaborators from other European institutes — the workshop seeks to strengthen scientific exchange, identify common research directions, and stimulate new collaborations on the dynamical evolution of disk galaxies across cosmic epochs.
