Excessive shift of the CMB acoustic peaks of the Cold Spot area
  Measurement of the acoustic peaks of the cosmic microwave background (CMB)
temperature anisotropies has been instrumental in deciding the geometry and
content of the universe. Acoustic peak positions vary in different parts of the
sky due to statistical fluctuation. We present the statistics of the peak
positions of small patches from ESA Planck data. We found that the peak
positions have significantly high variance compared to the 100 CMB simulations
with best-fit LambdaCDM model with lensing and Doppler boosting effects
included. Examining individual patches, we found the one containing the
mysterious "Cold Spot", an area near the Eridanus constellation where the
temperature is significantly lower than Gaussian theory predicts, displays
large synchronous shift of peak positions towards smaller multipole numbers
with significance lower than 1.11x 10^{-4}. The combination of large
synchronous shifts in acoustic peaks and lower than usual temperature at the
Cold Spot area results in a 4.73-sigma detection (significance p~ 1.11x
10^{-6}) against the LambdaCDM model. And it was already reported in Finelli et
al. (2016) that in the WISE-2MASS galaxy catalog at z<0.3 the Cold Spot region
is surrounded by surprisingly large underdense regions around 15 degs in
radius, which are found to be in the same square patch. Thus we propose there
is some extra localized unknown energy to stretch out the space in the
transverse direction around the Cold Spot area to simultaneously account for
the Cold Spot, excessive shift of the acoustic peaks, and the large underdense
regions.
