Fourier spectral analysis has been carried out on the quasar number count as a function of redshift calculated from the quasar data of the Sloan Digital Sky Survey DR6 data release. The results indicate that quasars have preferred periodic redshifts with redshift intervals of 0.258, 0.312, 0.44, 0.63, and 1.1. Within their standard errors these intervals are integer multiples 4, 5, 7, 10 and 20 of 0.062. Could this be indicative of an intrinsic redshift for quasars as has been suggested by some?
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=4 are visible. Their positions agree with the preferred redshift values predicted by the decreasing intrinsic redshift (DIR) model.
Evidence is presented for redshift quantization and variability as detected in global studies done in the rest frame of the cosmic background radiation. Quantization is strong and consistent with predictions derived from concepts associated with multidimensional time. Nine families of periods are possible but not equally likely. The most basic family contains previously known periods of 73 and 36 km s–1 and shorter harmonics at 18.3 and 9.15 km s–1.
Using new data for unassociated galaxies with wide H I profiles and values of period and solar motion predicted by Tifft and Cocke (1984), a periodicity has been found which is significant at the conventional 5 percent level. Together with Tifft's work on galaxy pairs and small groups, this result appears to provide evidence in favor of the hypothesis that measured galaxy redshifts occur in steps of a little more than 72 km/s or a simple multiple of this period.
Power spectrum analyses of the corrected redshifts are used to search for a significant periodicity in the prescribed range 70-75 km/s. No such periodicity is found for the dwarf irregulars, but there is a possible periodicity of about 71.1 km/s for the bright spirals. In a further exploratory study, the sample of 112 spirals is divided up according to environment. The spirals in high-density regions of the cluster show no quantization, whereas those in low-density regions appear to be partially quantized in intervals of about 71.0 km/s.
The present study investigates the notion that extragalactic redshifts are periodic in ranges around 24.2, 36.3, or 72.5 km/s for an independent sample of 89 nearby spirals, in the general field, with accurately determined heliocentric redshifts. A strong periodicity of about 37.2 km/s is found, against a white noise background, for an assumed solar vector coincidental, within the uncertainties, with that corresponding to the sun's probable motion around the Galactic Center. Comparison with sets of synthetic data simulating the overall characteristics of the real data show the periodicity to be present at a high confidence level.
Published observational data on galaxies of redshift z less than about 1000 km/s are compiled in extensive tables and diagrams and analyzed, searching for additional Local Group members among fainter higher-redshift galaxies. A concentration toward the center of the Local Group and a concentration associated with NGC 55, NGC 300, and NGC 253 are identified in the south Galactic hemisphere and characterized in detail. The galaxies near the centers of the concentrations are found to obey a quantization interval of Delta-cz0 = 72.4 km/s, as for the Local Group (Tifft, 1977); the accuracy of this finding is shown to be to within + or - 8.2 km/s (for galaxies with redshifts known to + or - 8 km/s) and to within 3-4 km/s (for a subset of galaxies with more accurately measured redshifts).
Samples of 97 and 117 high-precision 21 cm redshifts of spiral galaxies within the Local Supercluster were obtained in order to test claims that extragalactic redshifts are periodic (P36 km s–1) when referred to the centre of the Galaxy. The power spectral density of the redshifts, when so referred, exhibits an extremely strong peak at 37.5 km s–1. The signal is seen independently with seven major radio telescopes. Its significance was assessed by comparison with the spectral power distributions of synthetic datasets constructed so as to closely mimic the overall properties of the real datasets employed; it was found to be real rather than due to chance at an extremely high confidence level.
Persistent claims have been made over the last ~15yr that extragalactic redshifts, when corrected for the Sun's motion around the Galactic centre, occur in multiples of ~24 or ~36km/s. A recent investigation by us of 40 spiral galaxies out to 1000km/s, with accurately measured redshifts, gave evidence of a periodicity ~37.2-37.7km/s. Here we extend our enquiry out to the edge of the Local Supercluster (~2600km/s), applying a simple and robust procedure to a total of 97 accurately determined redshifts. We find that, when corrected for related vectors close to recent estimates of the Sun's galactocentric motion, the redshifts of spirals are strongly periodic (P~37.6km/s). The formal confidence level of the result is extremely high, and the signal is seen independently with different radio telescopes. We also examine a further sample of 117 spirals observed with the 300-foot Green Bank telescope alone. The periodicity phenomenon appears strongest for the galaxies linked by group membership, but phase coherence probably holds over large regions of the Local Supercluster.
A project intended to examine the long-standing claims that extragalactic redshifts are periodic or quantized was initiated some years ago at the Royal Observatory, Edinburgh. The approach taken is outlined, and the main conclusions to date are summarized. The existence of a galactocentric redshift quantization is confirmed at a high confidence level.
It is pointed out that the discrete velocities found by Tifft in galaxies are harmonically related to the discrete intrinsic redshifts found in quasars. All are harmonically related to the constant 0.062±0.001, and this is the fourth independent analysis in which the redshift increment 0.062 has been shown to be significant. It is concluded that there is a quantized component in the redshift of both quasars and galaxies that has a common origin and is unlikely to be Doppler-related.
A strong X-ray source only 8'' from the nucleus of the Seyfert 2 galaxy NGC 7319 in Stephan's Quintet has been discovered by Chandra. We have identified the optical counterpart and show that it is a QSO with ze = 2.114. It is also an ultraluminous X-ray source with LX = 1.5 × 1040 ergs s-1. From the optical spectra of the QSO and the interstellar gas of NGC 7319 together, we show that it is very likely that the QSO is interacting with the interstellar gas.
We present new spectroscopic observations of an old case of anomalous redshift--NGC 7603 and its companion. The redshifts of the two galaxies which are apparently connected by a luminous filament are z=0.029 and z=0.057 respectively. We show that in the luminous filament there are two compact emission line objects with z=0.243 and z=0.391. They lie exactly on the line traced by the filament connecting the galaxies. As far as we are aware, this is the most impressive case of a system of anomalous redshifts discovered so far.
Radio and optical evidence for activity in the spiral galaxy NGC 4319 is presented. NGC 4319 appears to be one of the first spirals to exhibit double lobe radio structure outside of the nuclear regions. The optical data show that (1) the quasar M205 is connected to the nucleus of NGC 4319 and (2) that a similarly connected region on the opposite side of the nucleus is expanding towards us with V ≡ 103km s-1. It is suggested that the unusual Hα/[N II] λ6583 ratio (≤0.3) indicates that the entire central (7 kpc diameter) disk of NGC 4319 has been shock excited by this activity.
New direct-imaging data are presented for the disturbed spiral galaxy NGC 4319 (z = 0.005) and the apparently connected quasar-like object Markarian 205 (z = 0.072). Image processing of this CCD data reveals (1) an almost continuous luminous connection extending from Mrk 205 into the nucleus of the spiral galaxy; (2) a corresponding feature on the opposite side of the disk, appearing to link a bright UV knot with the nucleus; and (3) extensive morphological peculiarities in NGC 4319 that are consistent with hypothesized explosive nuclear activity. These data support the conclusion that NGC 4319 is an active spiral galaxy that recently ejected Mrk 205 from its nucleus.

If red shift is not an indicator of distance, which I believe has been conclusively demonstrated that it is not by observational evidence, then we can reject the big bang as science and move on to looking at the universe as being steady in state. That is to say, the universe is infinite in size, it is ageless, it is timeless, and no big bang ever occurred. We are simply not privileged to know what caused the universe to exist or when it came into existence, it simply does. We must assume it is infinite in age as it is infinite in size.
