The same study also concludes that a "filter gap footprint" renders it impossible to verify or falsify the presence of a true redshift peak at Δ''z'' = 0.60.<ref>{{cite journal | last1 = Bell| first1 = M.

A 2006 review by Bajan ''et al.'' discovered weak effects of redshift periodization in data from the [[Local Group]] of galaxies and the [[Hercules Supercluster]]. They conclude that "galaxy redshift periodization is an effect which can really exist", but thatthough the evidence is not well established pending study of larger databases.<ref>{{cite journal |bibcode=2007PPNL....4....5B|arxiv=astro-ph/0606294 | title=On the Investigations of Galaxy Redshift Periodicity | journal=Physics of Particles and Nuclei Letters |date=2007 |volume=4 |issue=1 |pages=5–10 |first1=K. |last1=Bajan |first2=P. |last2=Flin |first3=W. |last3=Godlowski |first4=V.

A 2007 [[absorption spectroscopy|absorption spectroscopic]] analysis of quasars by Ryabinkov ''et al.'' observed a pattern of statistically significant alternating peaks and dips in the redshift range Δ''z'' = 0.0 − 3.7, though they noted no statistical correlation between their findings and Karlsson's formula.<ref>{{cite journal | last1 = Ryabinkov| first1 = A.
