Quantized Redshift and its Significance for Recent Observation

Abstract With the recent observational evidence in extragalactic astronomy, the interpretation of the nature of quasar redshift continues to be a research interest. Very high redshifts are being detected for extragalactic objects that are presumably very distant and young while also exhibiting properties that are characteristic of a more mature galaxy such as ours. According to Halton Arp and Geoffrey Burbidge, redshift disparities consist of an intrinsic component and are related to an evolutionary process. Karlsson observed redshift periodicity at integer multiples of 0.089 in log scale and Burbidge observed redshift periodicity at integer multiples of 0.061 in linear scale. Since Singular Value Decomposition based periodicity estimation is known to be superior for noisy data sets, especially when the data contain multiple harmonics and overtones, mainly irregular in nature, we have chosen it to be our primary tool for analysis of the quasar-galaxy pair redshift data. We have observed a fundamental periodicity of 0.051 with a confidence interval of 95% in linear scale with the site-available Sloan Digital Sky Survey Data Release 7 (SDSS DR7) quasar-galaxy pair data set. We have independently generated quasar-galaxy pair data sets from both 2dF and SDSS and found fundamental periodicities of 0.077 and 0.089, respectively, in log scale with a confidence interval of 95%.
