Observations of Large Scale Anisotropy and Cosmological Models

The Universe at large  scale  is statistically homogeneous and isotropic. However,

there are observations violating isotropy. I will start with some well established

anisotropy  observations and will show a few new results from NVSS and JVAS/CLASS data.

I will give a brief discussion on data sets and statistical method used for analysis. 

I  will  also present some  possible  models explaining  these large scale anisotropy  observations.
