Spontaneous scalarization of neutron stars in teleparallel gravity with derivative torsional coupling
Youcef Kehal, Khireddine Nouicer
We study neutron star configurations in a teleparallel gravity model featuring a scalar field coupled to both matter and torsion. In the Einstein frame, the theory includes a deriv…
Black holes and wormholes in sourceless three-dimensional conformal Killing gravity
Gerard Clement, Khireddine Nouicer
We derive all the sourceless solutions of three-dimensional conformal Killing gravity with two Killing vectors. Along with singular solutions and BTZ black holes, the stationary so…
Alleviating the and tensions in the interacting cubic covariant Galileon model
Sihem zabat, Youcef Kehal, Khireddine Nouicer
The interaction between dark matter and dark energy has become a focal point in contemporary cosmological research, particularly in addressing current cosmological tensions. This s…
Spherical symmetric solutions of conformal Killing gravity: black holes, wormholes, and sourceless cosmologies
Gérard Clément, Khireddine Nouicer
The most general set of static and spherically symmetric solutions for conformal Killing gravity coupled to Maxwell fields is presented in closed form. These solutions, depending o…
Farewell to Cotton gravity
Gérard Clément, Khireddine Nouicer
We reformulate our proof of the under-determination of Cotton gravity in terms of the Codazzi parametrization.
Cotton gravity is not predictive
Gérard Clément, Khireddine Nouicer
It is well-known that the theory of Cotton gravity proposed by Harada is trivially solved by all isotropic and homogeneous cosmologies. We show that this under-determination is mor…
