Yes. Future CMB experiments such as Advanced ACTPol and CMB-S4 should achievemeasurements with S/N of $> 0.1$ for the typical galaxies in redshift surveys.These measurements will provide complementary measurements of the growth rateof large scale structure $f$ and the expansion rate of the Universe $H$ togalaxy clustering measurements. This paper emphasizes that there is significantinformation in the anisotropy of the relative pairwise kSZ measurements. Weexpand the relative pairwise kSZ power spectrum in Legendre polynomials andconsider up to its octopole. Assuming that the noise in the filtered maps isuncorrelated between the positions of galaxies in the survey, we derive asimple analytic form for the power spectrum covariance of the relative pairwisekSZ temperature in redshift space. While many previous studies have assumedoptimistically that the optical depth of the galaxies $\tau_{\rm T}$ in thesurvey is known, we marginalize over $\tau_{\rm T}$, to compute constraints onthe growth rate $f$ and the expansion rate $H$. For realistic sure parameters,we find that combining kSZ and galaxy redshift survey data reduces themarginalized $1$-$\sigma$ errors on $H$ and $f$ by $\sim50$-$70\%$ compared tothe galaxy-only analysis.

Will Kinematic Sunyaev-Zel'dovich Measurements Enhance the Science Return from Galaxy Redshift Surveys?
