Two new samples of QSOs have been constructed from recent surveys to test the hypothesis that the redshift distribution of bright QSOs is periodic in log (1 + z). The first of these comprises 57 different redshifts among all known close pairs or multiple QSOs with image separations ≤10'', and the second consists of 39 QSOs selected through their X-ray emission and their proximity to bright, comparatively nearby active galaxies. The redshift distributions of the samples are found to exhibit…

Critical Examinations of QSO Redshift Periodicities and Associations with Galaxies in Sloan Digital Sky Survey Data
We have used the publicly available data from the Sloan Digital Sky Survey and 2dF QSO redshift survey to test the hypothesis that QSOs are ejected from active galaxies with periodic noncosmological
Selection Effects in the Redshift Distribution of Gamma-Ray Bursts and Associated Quasi-stellar Objects and Active Galaxies
Redshift distributions of extragalactic objects have been suggested to exhibit periodicities. But based on which periodicities are claimed, peaks and troughs have been shown to be artifacts of
On Quasar Distances and Lifetimes in a Local Model
It was shown previously from the redshifts and positions of the compact, high-redshift objects near the Seyfert galaxy NGC 1068 that they appear to have been ejected from the center of the galaxy in
The Sources of Gamma-Ray Bursts and Their Connections with QSOs and Active Galaxies
It is shown that the redshifts zo of ?-ray burst (GRB) sources, where they have been measured, together with the redshifts for seven quasars (QSOs) that lie very close to the positions of the
QSOs Associated with M82
The starburst/AGN galaxy M82 was studied by Dahlem, Weaver, and Heckman using X-ray data from ROSAT and ASCA as part of their X-ray survey of edge-on starburst galaxies. They found 17 unresolved hard
Further Evidence for Large Intrinsic Redshifts
An examination of the positions and redshifts of the compact QSO-like objects reported near the Seyfert 2 galaxy NGC 1068 has revealed many relationships that strongly suggest that the objects have
Distances of Quasars and Quasar-like Galaxies: Further Evidence That Quasi-stellar Objects May Be Ejected from Active Galaxies
If high-redshift quasi-stellar objects (QSOs) are ejected from the nuclei of low-redshift galaxies, as some have claimed, a large portion of their redshift must be intrinsic (non-Doppler). If these
The Field surrounding NGC 7603: Cosmological or non-cosmological redshifts?
We present new observations of the field surrounding the Seyfert galaxy NGC 7603, where four galaxies with different redshifts - NGC 7603 (z = 0.029), NGC 7603B (z = 0.057) and two fainter emission
SIX PEAKS VISIBLE IN THE REDSHIFT DISTRIBUTION OF 46,400 SDSS QUASARS AGREE WITH THE PREFERRED REDSHIFTS PREDICTED BY THE DECREASING INTRINSIC REDSHIFT MODEL
The redshift distribution of all 46,400 quasars in the Sloan Digital Sky Survey (SDSS) Quasar Catalog, Third Data Release (DR3), is examined. Six peaks that fall within the redshift window below z =
Study of Possible Local Quasars and Search for a Quasar-Stellar Connection. III. A Sample of 341 QSOs
A new sample of 341 possible local QSOs are presented, which are in the vicinity of low redshift galaxies. Physical characteristics of the sample quasars are determined and previously reported

A comparison of the spatial distribution of the 47 identified QSOs in the 3C and 3CR catalogs with the small-redshift galaxies contained in the Reference Catalog of Bright Galaxies shows that four
