We present near-infrared K-band images of 15 galaxies. We have performed a Fourier analysis on the spiral structure of these galaxies in order to determine their pitch angles and dust-penetrated arm classes. We have also obtained rotation curve data for these galaxies and calculated their shear rates. We show that there is a correlation between pitch angle and shear rate and conclude that the main...
We present a near infrared 2D Fourier analysis of the interacting pair of galaxies NGC 5394/95 to get insight on its morphology. Our analysis shows that NGC 5394 is a H2ß galaxy in the DP classification (Block and Puerari 1999). NGC 5395, in contrast, displays a very complex structure which needs a number of Fourier coefficients to be explained. A tightly wound m = 1 (DP class H1α) is the main structure,...
