    Absorption Lines in the Spectra of Quasi-stellar Objects (1968)

    Notes: [Auszug] We have calculated the probability that radiation from a remote object will pass through at least one intervening galaxy using various models of the universe4. For the sake of the present discussion we adopt the world model recently suggested by Solheim5 with a deceleration parameter g0= - 1-4 and ...

    Notes: Abstract It is assumed that the universe can be represented by low density Friedmann models with non-zero cosmological constant and long ages. By comparing theoretical and observational apparent magnitude-redshift relations, the rates of galaxy evolution required to force coincidence of these relations in visual light are deduced for each model. These rates are compared with various recent estimates of this effect and are also used to predict the slope of the bright end of the luminosity function of elliptical galaxies. Both the comparison and the prediction indicate that, unless the slope of the bright end of the luminosity function is considerably flatter than that produced by extrapolation, it is impossible to assign all of the difference between theory and present observations to evolutionary effects. Such an assignment could, however, be made if a dispersion in the luminosities of the most distant galaxies is found.

    Blackbody Radiation and the Eddington–Lemaître Universe (1967)

    Notes: [Auszug] This communication shows that such radiation could also be present in a universe which is of the Eddington-Lemaitre type4-that is, which expands from a finite static state in the infinite past. In contrast to the hot models mentioned, and the cold model described by Zeldovitch5, the modified ...
