 Title: Evidence of Quasi-linear Super-Structures in  the Cosmic Microwave Background and Galaxy Distribution
 Key Words: cosmic microwave background, cosmology, large scale structure of the univers
 Abstract: Recent measurements of hot and cold spots 
on the CMB sky suggest a presence of 
super-structures on (>100 Mpc/h) scales.  We develop a new
formalism to estimate the expected amplitude of temperature fluctuations due to the integrated Sachs-Wolfe (ISW) effect from prominent quasi-linear structures. Applying the developed tools to the observed ISW signals from voids and clusters in catalogs of galaxies at redshifts z<1, we find that they indeed 
imply a presence of quasi-linear super-structures
with a comoving radius 100~300Mpc/h and a
density contrast ~O(0.1). We find that the observed ISW signals are at odd with the concordant LCDM model that predicts Gaussian primordial perturbations at more than 3 sigma level. We also confirm that the mean temperature around the CMB cold spot in the southern Galactic hemisphere filtered by 
a compensating top-hat filter deviates from a mean value at 
nearly 3 sigma level, implying that a quasi-linear 
supervoid or an underdensity region surrounded by a massive wall 
may reside at low redshifts z<0.3.
