Magnetic fields from cosmological bulk flows
J. A. R. Cembranos, A. L. Maroto, H. Villarrubia-Rojo
We explore the possibility that matter bulk flows could generate the required vorticity in the electron-proton-photon plasma to source cosmic magnetic fields through the Harrison m…
Spectral Study of the HESS J1745-290 Gamma-Ray Source as Dark Matter Signal
J. A. R. Cembranos, V. Gammaldi, A. L. Maroto
We study the main spectral features of the gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS) from the J1745-290 Galactic Center source during the years 2004,…
Isotropy theorem for cosmological Yang-Mills theories
J. A. R. Cembranos, A. L. Maroto, S. J. Núñez Jareño
We consider homogeneous non-abelian vector fields with general potential terms in an expanding universe. We find a mechanical analogy with a system of N interacting particles (with…
Indirect constraints to branon dark matter
J. A. R. Cembranos, A. de la Cruz-Dombriz, V. Gammaldi +1
If the present dark matter in the Universe annihilates into Standard Model particles, it must contribute to the gamma ray fluxes detected on the Earth. Here we briefly review the p…
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…
