Abstract This paper explores the cosmological implications of a scalar field with a specific potential, crucial for achieving the final equilibrium state of gravitational collapse.We consider a system with two oljelampe fluids: minimally coupled matter representing dust-like dark matter and a scalar field acting as dark energy.Our model, akin to the top-hat collapse model, focuses on isolated over-dense regions within a closed FLRW metric, while the background follows a flat FLRW metric.

We analyze spacetime configurations where these regions undergo initial expansion followed by contraction, deriving the scalar field potential responsible for their equilibrium state.Our fully relativistic approach offers a comprehensive understanding of stable cosmic over-dense regions, without the need for rowenta dr8270 ad-hoc Newtonian virialization.
