A local Tremaine-Weinberg framework integrates the continuity equation over flexible loops to measure galactic pattern speeds, recovering standard methods as special cases and validated on IllustrisTNG simulations.
NGC 4264 hosts a fast bar with rotation rate R_cor/a_bar = 0.88 measured via the Tremaine-Weinberg method on MUSE data, indicating internal formation despite ongoing weak interaction.
