We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

In this paper we have assumed a weak-field regime to explore the gravitational lensed
photons in a 4 dimensional Einstein–Gauss–Bonnet gravity, which is very much in the …

Recently, a novel 4D Einstein–Gauss–Bonnet gravity was formulated by Glavan and Lin
(Phys Rev Lett 124 (8): 081301, 2020). Although whether the theory is well defined is …

We investigate the D→ 4 limit of the D-dimensional Einstein-Gauss-Bonnet gravity, where
the limit is taken with α˜=(D− 4) α kept fixed and α is the original Gauss-Bonnet coupling …

Recently, a novel 4D Einstein–Gauss–Bonnet gravity has been proposed by Glavan and Lin
(2020 Phys. Rev. Lett. 124 081301) by rescaling the coupling $\alpha\to\alpha/(D-4) $ and …

Recently, a non-trivial 4D Einstein-Gauss-Bonnet (EGB) theory of gravity, by rescaling the
GB coupling parameter as α/(D− 4), was formulated in [1], which bypasses Lovelock's …

The recent discovery of the novel four-dimensional static and spherically symmetric Gauss–
Bonnet black hole provides a promising bed to test Gauss–Bonnet gravity by using …

We reformulate the recently proposed regularized version of Lovelock gravity in four
dimensions as a scalar-tensor theory. By promoting the warp factor of the internal space to a …

The topological classification of critical points of black holes in 4D Einstein-Gauss-Bonnet
gravity coupled to Born-Infeld theory is investigated. Considered independently, Born-infeld …
