Abstract
⺠H i intensity fluctuation power spectrum for a sample of 18 spiral galaxies chosen from THINGS are estimated. ⺠Our analysis spans a large range of length-scales from â¼300 pc to â¼16 kpc across the entire galaxy sample. ⺠Power spectrum are well fitted by single power laws with the power law index in the range α = â1.9 to 1.5 for 60% of the galaxies. ⺠We find no significant correlation between α and the star formation rate, dynamical mass, H i mass or velocity dispersion of the galaxies.
