Recent observational evidence in extragalactic astronomy brings into question the nature of quasar redshifts. Very high redshifts are being detected in extragalactic objects that are assumed to be very distant and young while also exhibiting properties that are characteristic of more mature galaxies such as our Milky Way.
According to the hypothesis of Halton Arp and Geoffrey Burbidge, the redshifts of quasars include a discrete intrinsic component related to their age after ejection from a parent galaxy. See figure below.

The intrinsic redshifts exhibit periodicity according to Karlsson with integer values as multiples of 0.089 in log scale. Also Burbidge originally observed redshift periodicity at integer multiples of 0.061 in linear scale.

The Introduction of a new research paper Mal et al (2024)1 published in Research in Astronomy and Astrophysics, has an excellent summary of the situation in astronomy.
Hoyle & Narlikar (1966) observed the physical association of quasars and galaxies by noting numerous instances of a quasar and a galaxy in close astrometric proximity but with different redshifts, for instance, a quasar with z = 2.114 very close to the nucleus of the galaxy NGC 7319 with z = 0.022. Arp observed many such pair cases in which filaments connect the objects, including prominent ones (e.g., NGC 4319 and MRK 205; NGC 3067 and 3C 232). Some quasars exhibit jets of unknown nature (e.g., 3C 345 in the vicinity of NGC 6212), while in some cases moving structures are radio sources accompanied by optical jets.1

López-Corredoira & Gutiérrez (2004) observed two emission line objects with redshifts greater than 0.2 in the optical filament apparently connecting the Seyfert galaxy NGC 7603 with z = 0.029 to its companion NGC 7603B with z = 0.057, a possible example of anomalous redshift. These findings lead to the conclusion that quasars are ejected from galactic nuclei and that quasar redshift is largely an intrinsic parameter.
Mal et al (2024)1 used a method of Singular Value Decomposition based periodicity estimation, which is known to be superior for noisy data sets, especially when the data contain multiple harmonics and overtones. The authors chose that as their primary tool for analysis of the quasar-galaxy pair redshift data from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7).
They observed a fundamental periodicity of 0.051 with a confidence interval of 95% in linear scale the site-available SDSS DR7 quasar-galaxy pair data set. They independently generated quasar-galaxy pair data sets from both 2dF and SDSS and found fundamental intrinsic redshift periodicities of 0.077 and 0.089, respectively, in log scale with a confidence interval of 95%. These results build on the work of Fulton and Arp (2012)2 and Fulton, Arp and Hartnett (2018)3.
What does it mean? It means that the standard Hubble redshift-distance relation for all high redshift astrophysical objects is wrong. If that is wrong then it brings into doubt the entire edifice upon which the standard big bang cosmology is based.
