A search for concentric circles in the 7 year WMAP temperature sky maps

Wehus & Eriksen 2011: rings reproduced; simulations disagree; sky consistent with ΛCDM

what the source states

An independent search employing both χ² statistics and matched filters: "We do reproduce the claimed ring structures observed in the WMAP data as presented by Gurzadyan and Penrose, thereby verifying their computational procedures. However, the results from our simulations do not agree with those presented by Gurzadyan and Penrose. On the contrary we obtain a substantially larger variance in our simulations, to the extent that the observed WMAP sky maps are fully consistent with the LCDM model as measured by these statistics."

what we infer

Read against CCC-C001 this is a confirmation (the features are real outputs of the procedure); read against CCC-C002 it is a direct contradiction, and it localizes the disagreement precisely where CCC-C003 says it lives — in the simulated null, not in the data.

limitations

• Uses ΛCDM-spectrum simulations, which the proponents dispute as the appropriate null (CCC-C003) — the force of this record depends on that methodological question.
