Enhancing bispectrum estimators for galaxy redshift surveys with velocities

We forecast the ability of bispectrum estimators to constrain primordial non-Gaussianity using future photometric galaxy redshift surveys. A full-sky survey with resolution $\sigma_z/(1+z)=0.05$ in range $0.2<z<2$ can provide constraints $\sigma(f^\mathrm{local}_\mathrm{NL})=3.4$, $\sigma(f^\mathrm{equil}_\mathrm{NL})=15$, and $\sigma(f^\mathrm{orth}_\mathrm{NL})=17$ for local, equilateral, orthogonal shapes respectively, delivering on non-Gaussianities competitive those from cosmic microwave background. generalize these results by deriving a scaling relation amplitude as function error, depth, sky coverage, nonlinear scale cutoff. Finally, we investigate impact that calibration errors largest scales will have constraining power experiments. show peculiar velocities reconstructed via kinetic Sunyaev Zeldovich tomography be used mitigate constraints.
