Query: A new consistency test for $\Lambda$CDM cosmology using galaxy surveys   We propose a new consistency test for the $\Lambda$CDM cosmology using
baryonic acoustic oscillations (BAO) and redshift space distortion (RSD)
measurements from galaxy redshift surveys. Specifically, we determine the peak
position of $f\sigma_8(z)$ in redshift $z$ offered by a RSD measurement, and
compare it to the one predicted by the BAO observables assuming a flat
$\Lambda$CDM cosmology. We demonstrate this new test using the simulated data
for the DESI galaxy survey, and argue that this test complements those using
the background observables alone, and is less subject to systematics in the RSD
analysis, compared to traditional methods using values of $f\sigma_8(z)$
directly.
