We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by applying PCA on the spectral maps in CO, CO, HCO J =1−0, and CS J =2−1. First, the scaling relations derived from PCA of the CO maps show that the velocity difference (δv) for a given spatial scale (L) is the highest in the integral shaped filament (ISF) and L1688, where the most active star formation occurs in the two… Expand
