Hello,
What does the Faber Jackson relation tells? Does it establish the relation between: higher the Luminosity, higher the velocity dispersion? Does it calculate in Elliptical galaxies? What does TullyFisher relation explains?  Shounak

Faber Jackson relation
Is Tully Fisher model used in calculating the relation between luminosity and dispersion velocity in spiral galaxy?
Is Tully Fisher model and Faber Jackson are same except they are used in spiral and elliptical galaxy? What model is used to calculate irregular galaxies?
