Reconstruction of the scalar field potential in nonmetricity gravity through Gaussian processes
Gaurav N. Gadbail, Sanjay Mandal, P. K. Sahoo +1
The accelerated expansion of the universe has been widely confirmed, posing challenges to the standard CDM model, particularly the cosmological coincidence problem. This has mot…
Charged Fuzzy Dark Matter Black Holes
Z. Yousaf, Bander Almutairi, S. Khan +1
We investigate the impact of fuzzy dark matter (FDM) on supermassive black holes (SMBHs) characterized by a spherical charge distribution. This work introduces a new class of spher…
Orthogonal Splitting in Degenerate Higher-order Scalar-tensor Theories
Z. Yousaf, N. Z. Bhatti, H. Asad +2
We explore a comprehensive analysis of the formalism governing the gravitational field equations in degenerate higher-order scalar-tensor theories. The propagation of these theorie…
Completely Deformed Complexity-free Anisotropic Fluid Sphere
Z. Yousaf, Kazuharu Bamba, M. Z. Bhatti +1
In this work, we investigate the emergence of compact, anisotropic stellar structures through the gravitational decoupling scheme within the framework of complete geometric deforma…
A Double-Sine-Gordon Early Universe
Behnoush Afshar, Marziyeh Peyravi, Kazuharu Bamba +1
A solitonic model of the early universe is introduced by employing the Double-Sine-Gordon (DSG) potential. The model predicts the appropriate number of e-foldings () required…
Imprints of dark matter on the structural properties of minimally deformed compact stars
Z. Yousaf, Kazuharu Bamba, Bander Almutairi +2
In this manuscript, we investigate the possibility of constructing anisotropic dark matter compact stars motivated by the Einasto density profile. This work develops analytical sol…
