An Anomaly in the Angular Distribution of Quasar Spectra
  Quasars provide our farthest-reaching view of the Universe. The Sloan Survey
now contains over 100,000 quasar candidates. A careful look at the angular
distribution of quasar spectra shows a surprising "bullseye" pattern on the sky
toward (RA, Dec) ~ (190{\deg}, 0{\deg}) for all wavelengths from UV through
infrared. The angular distribution of the shift in the UV suggests a large
peculiar velocity vp toward that direction. However, the size of the shift
would indicate a vp ~0.2 c, which is two orders of magnitude larger than
measures of our peculiar velocity from nearby galaxies and cosmic microwave
background (CMB) measurements. The angular pattern and size of the shift is
very similar for all wavelengths, which is inconsistent with a Doppler shift.
The shift is also too large to explain as a systematic error in the quasar
magnitudes. The anomaly appears to be a very large hotspot in the Universe. Its
direction is close to that of the reported anomalies in the CMB, the so-called
"axis of evil". The angular pattern of the shift and its redshift dependence
are consistent with the existence of an expanding bubble universe in that
direction, which could also explain the CMB anomalies.
