Gamma-ray and neutrino fluxes from Heavy Dark Matter in the Galactic Center
V. Gammaldi, J. A. R. Cembranos, A. de la Cruz-Dombriz +2
We present a study of the Galactic Center region as a possible source of both secondary gamma-ray and neutrino fluxes from annihilating dark matter. We have studied the gamma-ray f…
Detection of branon dark matter with gamma ray telescopes
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +1
Branons are new degrees of freedom that appear in flexible brane-world models corresponding to brane fluctuations. These new fields can behave as standard weakly interacting massiv…
Comment on "Viable singularity-free f(R) gravity without a cosmological constant" [arXiv:0905.1941]
A. de la Cruz-Dombriz, A. Dobado, A. L. Maroto
A modified f(R) gravity model has been recently proposed in Phys. Rev. Lett. 102, 221101 (2009) [arXiv:0905.1941] whose cosmological behaviour is clearly distinguishable from LCDM.…
Black Holes in f(R) theories
A. de la Cruz-Dombriz, A. Dobado, A. L. Maroto
In the context of theories of gravity, we address the problem of finding static and spherically symmetric black hole solutions. Several aspects of constant curvature solutio…
Cosmological density perturbations in modified gravity theories
A. de la Cruz-Dombriz, A. Dobado, A. L. Maroto
In the context of f(R) theories of gravity, we study the cosmological evolution of scalar perturbations by using a completely general procedure. We find that the exact fourth-order…
On the evolution of density perturbations in f(R) theories of gravity
A. de la Cruz-Dombriz, A. Dobado, A. L. Maroto
In the context of theories of gravity, we study the evolution of scalar cosmological perturbations in the metric formalism. Using a completely general procedure, we find the…
