The Axis of Evil revisited
In light of the three-year data release from WMAP we re-examine the evidence for the “Axis of Evil”. We discover that previous frequentist methods are not robust with respect to the data-sets available and different treatments of the galactic plane. We identify the cause of the instability and show that this result is not a weakness of the data. This is further confirmed by exhibiting an altern...
متن کاملThe axis of evil - a polarization perspective
We search for an unusual alignment of the preferred axes of the quadrupole and octopole, the so-called axis of evil, in the CMB temperature and polarization data from WMAP. We split the temperature and polarization maps into a part correlated with the respective other map, and a part uncorrelated with that. We then determine the preferred axes for the quadrupole and octopole in all four of thos...
متن کاملLocal Pancake Defeats Axis of Evil
Among the biggest surprises revealed by COBE and confirmed by WMAP measurements of the temperature anisotropy of the CMB are the anomalous features in the 2-point angular correlation function on very large angular scales. In particular, the l = 2 quadrupole and l = 3 octopole terms are surprisingly planar and aligned with one another, which is highly unlikely for a statistically isotropic Gauss...

INTRODUCTION “[D]eath is different.” When used to punish, death taps society’s most primal urges. It is meant to be a deterrent for potential offenders, triggering in them the innate reflex for self-preservation. For society, it is meant to feed the primal desire for retribution. For these very reasons, it is often claimed that death is only reserved for the worst of the worst. However, in tryi...
متن کاملSee no evil, hear no evil….
A 32-year-old woman presented with right-sided visual loss, hearing loss and diffuse headache. Examination confirmed CN-II, V1/2, and VIII neuropathies. MRI showed an infiltrative skull-base process involving the pachymeninges. Serology and histopathology confirmed idiopathic hypertrophic pachymeningitis.
