Relativistic cosmological large scale structures at one-loop 

The large scale structure bispectrum in the squeezed limit couples large with small scales. Since relativity is important at large scales and non-linear loop corrections are important at small scales, the proper calculation of the observed bispectrum in this limit requires a non-linear relativistic calculation. I will introduce some ideas of theory of large scale structure of the universe and what we found using  the relativistic cosmological perturbation theory.
