I have just submitted a paper with Fabian and Chris to arXiv! In this paper, we have calculated the galaxy power spectrum on very large scales, scales near the horizon. On those large scales, gneral relativistic effect is important and has to be taken into account. This was also a subject of my talk in the non-Gaussianity conference in last May at Ann Arbor, Michigan. Why does it take two months to finish up? Because we have much more to say to clarify the issues! We hope that everything becomes clear in this paper!! :)

Two of my papers with Vincent and Fabian are out to arXiv (1, 2) today. In paper 1, we have presented the new formula for the scale dependent bias from general primordial non-Gaussianity models. And in paper2, we compare it to the N-body simulations of 1) gNL model, 2) otrhogonal model, and 3) scale dependent fNL model, and show that the new formula can actually explain the discrepancies we have seen thus far between high-peak theory and N-boy simulations. If you are working on the non-Gaussianity model, you must use the new formula!

My paper with Fabian and Emiliano is out to arXiv today. This paper is about the non-Gaussian effect on the correlation of the non-linear tracers of the projected density field, e.g. peaks in weak lensing convergence field. The non-Gaussian effects on such kind of observables are suppressed compare to those of the non-linear tracers of three-dimensional density field due to projection: as long as the width of the projection kernel is greater than the correlation length (~55 [Mpc/h]), the non-Gaussianity signal is Gaussianized due to the central limit theorem (For those projections, we are basically stacking many 'uncorrelated' slab of 2D non-Gaussian density fields.). This is one of the importnt points of the paper, but it contains even more fruitful/interesting physics in it. You should read this!! :)
