Abstract: | The previous work (He, 2001) on image analysis of over one hundred nearby galaxies indicates that for any spiral galaxy image
of small inclination there is evidence of two sets of iso-ratio curves in different scales which, like curvilineal coordinate
lines, expand over different galaxy components. This result sets constraint on galaxy patterns and a general equation which
carries this constraint is presented in the current paper. The equation has clear geometrical meaning. Its much simplified
version which applies to galaxy arms, when solved, may be a guidance to understanding galaxy patterns.
This revised version was published online in July 2006 with corrections to the Cover Date. |
