The Morphological Luminosity Function
1988We obtain the morphological luminosity function for galaxies assuming that they form at high density regions of a filtered Gaussian random field. We compare our results with some observations of the LF for E and E+SO galaxies. Using scale-free spectra, we obtain bell-shaped curves that follow the observations.

The radio luminosity function and the luminosity diameter function of extragalactic radio sources
Astronomische Nachrichten, 1971AbstractOn the basis of a radio index‐surface brightness diagram recently published, the luminosity function and the luminosity diameter function are obtained. The uncertainties due to the incompleteness of the sample are of the same order as the statistical uncertainties.

The Quasar Luminosity Function
1993Recent work on the quasar luminosity function at radio, optical and X-ray wavelengths is reviewed. It is demonstrated that the evolution of the quasar luminosity function in all three regimes is marked by a strong and approximately similar power-law increase in luminosity, L ∝ (1 + z) 3±0.5, between the present epoch and z ≈ 2.
