Exotic Spinor Deformation of a Schwarzschild Black Hole: Perturbations and Stability
Luís Rodolfo dos Santos Filho, Bertha Cuadros-Melgar
In this work we investigate how exotic spinorial topology modifies the propagation of fermionic modes in the Schwarzschild geometry. By incorporating a topological gradient, $\part…

21-cm Brightness Temperature in a Unified-Dark-Sector Horndeski Theory
Bertha Cuadros-Melgar, Thanasis Karakasis, Eleftherios Papantonopoulos +1
We investigate the impact of scalar-tensor theories on the 21cm brightness temperature. We consider a specific model in Horndeski scalar-tensor theory in which dark matter and dark…
