Simpson and Visser recently proposed a phenomenological way to avoid some kinds of
space-time singularities by replacing a parameter whose zero value corresponds to a …

The so-called black-bounce mechanism of singularity suppression, proposed by Simpson
and Visser, consists of replacing the spherical radius r in the metric tensor with r 2+ a 2, a …

Thanks to the recent advent of the event horizon telescope (EHT), we now have the
opportunity to test the physical ramifications of the strong-field near-horizon regime for …

We apply the Simpson-Visser phenomenological regularization method to a cylindrically
symmetric solution of the Einstein-Maxwell equations known as an inverted black hole. In …

We explore the possibility of embedding regular compact objects with an (anti-) de Sitter [(A)
dS] core as solutions of Einstein's gravity minimally coupled to a real scalar field. We …

We explore the possibility of embedding regular compact objects with (anti) de Sitter ((A) dS)
core as solutions of Einstein's gravity minimally coupled to a real scalar field. We consider …

The 4D gravitational model with a real scalar field, Einstein and Gauss–Bonnet terms is
considered. The action contains the potential and the Gauss–Bonnet coupling function. For …

This article shows the possibilities of using the scalar-tensor theory in finding the kinetic
coupling function and potential of the non-singular static spherical-symmetric metric. In this …
