Globular clusters are among the oldest stellar populations in the Milky Way; consequently,
they also host some of the oldest known stellar-mass black holes, providing insight into …

We show that—in the framework of general relativity (GR)—if black holes (BHs) are
singularity-free objects, they couple to the large-scale cosmological dynamics. We find that …

Recent work has suggested that black holes (BHs) could be cosmologically coupled to the
accelerated expansion of the Universe, potentially becoming a candidate for origin of dark …

It is shown that an exactly static and spherically symmetric black hole event horizon cannot
be embedded in a time-dependent geometry. Forcing it to do so results in a naked null …

We discuss exact regular compact object solutions in higher-dimensional extensions of
general relativity sourced by a phantom scalar field in arbitrary D spacetime dimensions (D> …

Coupling of black hole mass to the cosmic expansion has been suggested as a possible
path to understanding the dark energy content of the Universe. We test this hypothesis by …

Observations of elliptical galaxies suggest that black holes (BHs) might serve as dark energy
candidates, coupled to the expansion of the Universe. According to this hypothesis, the …

We test the possibility that the black holes (BHs) detected by LIGO-Virgo-KAGRA (LVK) may
be cosmologically coupled and grow in mass proportionally to the cosmological scale factor …

There has recently been some considerable interest expressed in a highly speculative
model of black-hole evolution—allegedly by a postulated direct coupling between black …
