Evidence in favour of density wave theory through age gradients observed in star formation history maps and spatially resolved stellar clusters
Quasi-stationary density wave theory predicts the existence of an age gradient across the spiral arms with a phase crossing at the corotation radius. We have examined evidence for such age gradients using star formation history (SFH) maps derived from lightning, a spectral energy distribution fittin...
