Stationary Density Wave Theory predicts the existence of an age gradientacross the spiral arms with a phase crossing at the co-rotation radius. Usingstar formation history (SFH) maps of 12 nearby spiral galaxies derived from\textsc{LIGHTNING} \citep{Eufracio:2017}, a spectral energy distribution (SED)fitting procedure, and by using \textsc{Spirality} \citep{Shield:2015} a\textsc{MATLAB}-based code which plots synthetic spiral arms over \textsc{FITS}images, we have found a gradual decrement in pitch angles with increasing age,thus providing us with evidence in favour of the Stationary Density WaveTheory. We have also used azimuthal offsets of spatially resolved stellarclusters in 3 LEGUS galaxies to observe age trends.
