The interplay between cosmological expansion and local attraction in a gravitationally bound system is revisited in various regimes. First, weakly gravitating Newtonian systems are considered, followed by various exact solutions describing a relativistic central object embedded in a Friedmann universe. It is shown that the ``all or nothing'' behaviour recently discovered (i.e., weakly coupled systems are comoving while strongly coupled ones resist the cosmic expansion) is limited to the de Sitter background. New exact solutions are presented which describe black holes perfectly comoving with a generic Friedmann universe. The possibility of violating cosmic censorship for a black hole approaching the Big Rip is also discussed.

Evaporating cosmologically coupled black holes
If a black hole's mass grows with cosmic expansion, Hawking evaporation is slowed or reversed, weakening gamma-ray bounds on primordial black holes.

Positive neutrino masses with DESI DR2 via matter conversion to dark energy
A model where stellar collapse to cosmologically coupled black holes converts baryons into dark energy, fit to DESI DR2 and Planck data, yields a positive summed neutrino mass around 0.05 to 0.11 eV, in agreement with...

Static Dark Fluid Thin Shells in Schwarzschild-de Sitter Spacetimes: Stability and Black Hole Shadows
Stable static dark-fluid shells separating two Schwarzschild–de Sitter spacetimes exist only for m_+/m_->1 and arise at three scales, imprinting observable black-hole shadow deviations.

Black Hole Persistence in Scalar Tensor Theories
A perturbative scalar-tensor construction yields an evolving horizon of size proportional to the perturbation parameter that persists through a radiation-dominated bounce but evolves asymmetrically.
