Testing the nature of dark compact objects: a status report
Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Observations have found black holes spanning 10 orders of magnitude in mass across most
of cosmic history. The Kerr black hole solution is, however, provisional as its behavior at …

Novel black-bounce spacetimes: wormholes, regularity, energy conditions, and causal structure
We develop a number of novel “black-bounce” spacetimes. These are specific regular black
holes where the area radius always remains nonzero, thereby leading to a “throat” that is …

Phenomenological aspects of black holes beyond general relativity
While singularities are inevitable in the classical theory of general relativity, it is commonly
believed that they will not be present when quantum gravity effects are taken into account in …

[HTML][HTML] Anisotropic quark stars in Einstein-Gauss-Bonnet theory
Recent progress in the determination of both masses and radii of neutron stars has put
strong constraints on the equation of state (EoS) above the nuclear saturation density. Within …

Anisotropic stars as ultracompact objects in general relativity
Anisotropic stresses are ubiquitous in nature, but their modeling in general relativity is poorly
understood and frame dependent. We introduce the first study on the dynamical properties …

Stable and self-consistent compact star models in teleparallel gravity
GGL Nashed, S Capozziello - The European Physical Journal C, 2020 - Springer
In the framework of Teleparallel Gravity, we derive a charged non-vacuum solution for a
physically symmetric tetrad field with two unknown functions of radial coordinate. The field …
