Cosmological non-Gaussianity

I will discuss two types of non-Gaussianity in the CMB -- primordial and that produced by gravitational lensing. First I will talk about the study of non-Gaussianity generated during the epoch of inflation. In the second part, I will discuss the techniques which use the non-Gaussianity generated by gravitational lensing to constrain the dark matter power spectrum. Then I will overview current efforts to use the final ACBAR datasets to make the first detection of the convergence power spectrum using the CMB.
