Fun with Physics
Here is a recent paper posted to arXiv.org, I thought
the title alone was worth a post, and as a bonus at no extra cost, you get the complete abstract. == astro-ph/0502237: Title: The axis of evil Authors: Kate Land, Joao Magueijo We examine previous claims for a preferred axis at $(b,l) approx (60,-100)$ in the cosmic radiation anisotropy, by generalizing the concept of multipole planarity to any shape preference (a concept we define mathematically). Contrary to earlier claims, we find that the amount of power concentrated in planar modes for $\ell=2,3$ is not inconsistent with isotropy and Gaussianity. The multipoles' alignment, however, is indeed anomalous, and extends up to $\ell=5$ rejecting statistical isotropy with a probability in excess of 99.9%. There is also an uncanny correlation of azimuthal phases between $\ell=3$ and $\ell=5$. We are unable to blame these effects on foreground contamination or large-scale systematic errors. We show how this reappraisal may be crucial in identifying the theoretical model behind the anomaly. == WARNING - I have no idea if the authors are arXiv kooks or simply have a flair for a fancy title. Dark skies! tom -- We have discovered a therapy ( NOT a cure ) for the common cold. Play tuba for an hour. |
