The obvious flaw in their analysis is that they select quasars based on their absolute luminosity, a luminosity calculated using the LCDM framework. What they effectively measure is that the quasar temporal variability scales as (Luminosity)^1.28, which is consistent with the data in reference [19] Hawkins ApJ 553 (2), p. L97, 2001. A second flaw in their analysis is that quasars are closer than the cosmological distances implied by their redshift (see Fulton, etc.) This also produces an overestimation of their luminosity by some power of (1+z) that is not included in their analysis. |

"Detection of the Cosmological Time Dilation of High Redshift Quasars"
by Geraint F. Lewis and Brendon J. Brewer
http://arxiv.org/abs/2306.04053
It is notable that author Geraint Lewis is deeply worried that someone will beat the Big Bang. In this work, he cites papers from three ACG members.

"However, it has been claimed that the variability displayed by quasars over a broad range of redshifts does not show the expected cosmological time dilation[...] This has led to the suggestion that quasar variability is not intrinsic, but is due to microlensing due to the presence of cosmologically distributed black holes[...] Others have stated that this points to more fundamental issues with our cosmological ideas [e.g. 23–25]"
"Hence, as well as demonstrating the claim that the lack of the redshift dependence of quasar variability represents a significant challenge to the standard cosmological model, this analysis further indicates that the properties of quasars are consistent with them being truly cosmologically distant sources."
"This has an immediate impact on various claims, such as the presence of a cosmologically significant population of microlensing black holes [...] or more esoteric ideas about the framework of the universe [39], and is further evidence that we inhabit an expanding relativistic universe."
