We analyse the history of modern cosmology based on the redshift phenomenon and on the cosmic background radiation (CBR). We show the models of different authors for the interpretation of the redshift and how the tired light models predicted the correct value of 2.7 K temperature previous to Gamow and collaborators.

On the Nature of the Redshifts of the Twin Quasars with Discrepant Redshifts
Publications of the Astronomical Society of Australia, 1991AbstractWe examine the nature of the redshifts of twin quasars with discrepant redshifts (θ < 100 arcsec, Δz ≥ 0.5) by considering their Hubble diagram. If such twins are physically associated one expects a large scatter in their Hubble diagram. However, we find a statistically significant linear correlation between log (cz) and Vc magnitudes of ...

Redshift Quantization — A Review
Astrophysics and Space Science, 1995Redshift quantization has three main facets: 1) the internal organization of galaxies, 2) differential effects between galaxies in physical systems, 3) global effects linking all galaxies and cosmology. The subject originated as an outgrowth of redshift correlation studies including studies of internal kinematics of galaxies.

Zooming in on the Redshift Problem
Astrophysics and Space Science, 1996Scientific inference offers a way to help organize and clarify our thinking about controversial areas of science such as the redshift problem. Scientists typically devote considerable effort to evaluating the probability that data relevant to a controversial area may be due to the ”null hypothesis” (i.e. that there is no new phenomenon). However, it is

Damped Lyman-? systems (DLAs), the highest HI column density absorbers seen in QSO spectra, are believed to arise in the precursors of present-day galaxies [1]. Despite their importance in the context of galactic evolution, the typical size and structure of DLAs (as well as physical conditions in them) have long been issues of much controversy.

Redshifts of Companion Galaxies
Nature, 1970SINCE 1966 (ref. 1) there has been observational evidence2–4 that quasi-stellar radio sources (QSRs) and compact radio galaxies are ejected from galaxies. Whatever distance scale one uses, one of the characteristics of QSRs and compact radio galaxies is that a great deal of energy is compressed into very small dimensions. Unless very special conditions

It is well known that, due to the general expansion of the universe, all distant extragalactic objects (galaxies, quasars, etc.) are receding from us in space with high speed and that the observed recession velocity increases with distance. In the framework of a cosmological model, the sole measurement of the spectral redshift z of an extragalactic ...
