A New Correlation between Galaxy Stellar Masses and Spiral Arm

We present a new relation between pitch angle of spiral arm (a parameter of the tightness of spiral structure) and the galaxy stellar masses. Taken both with the result that stellar mass seems to determine pitch angle of spiral arm, one would anticipate a correlation to exist between pitch angle of...
