Limits on fNL<br />
• fNL = 32 ± 21 (68%C.L.) from WMAP 7-year data<br />
• Planck’s CMB data is expected to yield ΔfNL=5.<br />
• fNL = 27 ± 16 (68%C.L.) from WMAP 7-year data<br />
combined with the limit from the large-scale<br />
structure (by Slosar et al. 2008)<br />
Komatsu et al. (2011)<br />
• Future large-scale structure data are expected to<br />
yield ΔfNL=1.
