The photographic images of a carefully selected sample of about 16,000 galaxies have been digitized, and an extensive set of photometric parameters has been determined. These data allow a reanalysis of the effective transparency using the measured surface brightness profiles for much larger, more strictly defined samples. Several tests provide evidence

Bisymmetric Spiral Magnetic Fields in Spiral Galaxies
1987A radio polarization analysis was presented in 1978 by TOSA and FUJIMOTO [1] to determine a large-scale configuration of magnetic fields in the spiral galaxy M51. On the basis of the distributions of planes of polarization at 6 cm and 21 cm [2], they determined the rotation measures (RMs) of the Faraday effect and the intrinsic polarization angles. The

Phenomenology of Spiral Galaxies
1975Galaxies have probably been formed from fluctuations in density and motion in the universe. Many cosmologists have suggested that the separation into individual units took place around the time of decoupling of matter and radiation, when the radius of the universe was about 1/1000th of the present radius.
