• Studying the cosmological apparent horizon with quasistatic coordinates

This article aims at a natural generalization of the static coordinates to the $(n + 1)$-dimensional Friedmann–Lemaître–Robertson–Walker (FLRW) Universe. After demonstrating a no-go theorem, we put forward the quasistatic coordinates for the FLRW Universe. Then, the quasistatic coordinates are utilized to study the unified first law and the scalar-type perturbations on the cosmological apparent horizon.
