We present new, exact, rotating and accelerating solutions within the framework of five-dimensional Einstein-Gauss-Bonnet theory at the Chern-Simons point. The rotating solutions describe black holes characterized by a single rotation parameter, a ma

Abstract In this work, we propose a four-dimensional gauged Wess-Zumino-Witten model, obtained as a dimensional reduction from a transgression field theory invariant under the N $$ \mathcal{N} $$ = 1 Poincaré supergroup. For this purpose, we conside

Abstract In this paper, we formulate the Mimetic theory of gravity in first-order formalism for differential forms, i.e., the mimetic version of Einstein-Cartan-Sciama-Kibble (ECSK) gravity. We consider different possibilities on how torsion is affec

Abstract In this work, we study some thermodynamical aspects associated with torsion in a flat FLRW spacetime cosmic evolution. By implementing two Ansatze for the torsion term, we find that the model admits a phantom regime or a quintessence behavio

Abstract In order to study gravitational waves in any realistic astrophysical scenario, one must consider geometry perturbations up to second order. Here, we present a general technique for studying linear and quadratic perturbations on a spacetime w

The current article offers a mathematical toolkit for the study of waves propagating on spacetimes with nonvanishing torsion. The toolkit comprises generalized versions of the Lichnerowicz–de Rham and the Beltrami wave operators, and the Weitzenbö

When scientists engage in Public Understanding of Science to communicate their research to lay audiences, a common suggestion is to structure their talk around storytelling. Thus, it is crucial to know the actual effectiveness of storytelling in scie

The $\mathcal{N}=1$ AdS-Lorentz superalgebra is studied and its relationship to semigroup expansion developed. Using this mathematical tool, the invariant tensors and Casimir operators are found. In terms of these invariants, a three-dimensionnal Che
