A well-known example is the reconstruction technique for baryonic acoustic oscillations (BAO) [330{333]. Presently, reconstruction is performed using linear theory or Zel’dovich approximation [334]. On the other hand, a more accurate technique will ultimately lead to better bounds on dark en”

The cosmological analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure (2019, background): “While there is a plethora of perturbative approaches to LSS, dating back to the time of Zeldovich [11], it should be stressed that there can be only one correct perturbative approach.”
The effect of neutrinos on the matter distribution as probed by the intergalactic medium (2010, methodology): “ into two particles, giving them half the original mass and equal but opposite thermal velocities. However, we found this to have no inﬂuence on our results. We have used the Zel´dovich approximation [36] to generate initial conditions. We acknowledge that the use of a second-order Lagrangian pertur”
