We review the number counts to second order concentrating on the terms which dominate on sub horizon scales. We re-derive the result for these terms and compare it with the different versions found in the literature. We generalize our derivation to higher order terms, especially the third order number counts which are needed to compute the 1-loop contribution to the power spectrum.

Tetrad formalism for exact cosmological observables
The paper derives exact, coordinate-independent equations for cosmological observables on a new 'observer space-time' manifold, using tetrads to track the observer frame.

Galaxy number counts at second order: an independent approach
The authors present a new, independent derivation of the second-order relativistic galaxy number count in a flat expanding universe, but they only validate it at linear order against previous work.
