A Proposed Mechanism for the Intrinsic Redshift and its Preferred Values   Purportedly Found in Quasars Based on the Local-Ether Theory
  Quasars of high redshift may be ejected from a nearby active galaxy of low redshift. This physical association then leads to the suggestion that the redshifts of quasars are not really an indication of their distances. In this investigation, it is argued that the high redshift can be due to the gravitational redshift as an intrinsic redshift. Based on the proposed local-ether theory, this intrinsic redshift is determined solely by the gravitational potential associated specifically with the celestial object in which the emitting sources are placed. During the process with which quasars evolve into ordinary galaxies, the fragmentation of quasars and the formation of stars occur and hence the masses of quasars decrease. Thus their gravitational potentials and hence redshifts become smaller and smaller. This is in accord with the aging of redshift during the evolution process. In some observations, the redshifts of quasars have been found to follow the Karlsson formula to exhibit a series of preferred peaks in their distributions. Based on the quasar fragmentation and the local-ether theory, a new formula is presented to interpret the preferred peaks quantitatively.
