  • We discussed the physical background of the unified scaling law in spiral galaxies, and qualitatively obtained the power index of the empirical relation among the luminosity L, radius R and the rotation velocity V. We also discussed the possible causes for the data dispersion on the plane in three-dimensional space of these parameters.

Physical Background of the Unified Scaling Law in Spiral Galaxies

Abstract: We discussed the physical background of the unified scaling law in spiral galaxies, and qualitatively obtained the power index of the empirical relation among the luminosity L, radius R and the rotation velocity V. We also discussed the possible causes for the data dispersion on the plane in three-dimensional space of these parameters.
