Testing the EoS of dark matter with cosmological observations
Arturo Avelino, Norman Cruz, Ulises Nucamendi
We explore the cosmological constraints on the parameter w_dm of the dark matter barotropic equation of state (EoS) to investigate the "warmness" of the dark matter fluid. The mode…
Reconstruction of the interaction term between dark matter and dark energy using SNe Ia, BAO, CMB, H(z) and X-ray gas mass fraction
Freddy Cueva Solano, Ulises Nucamendi
Recently, in [1] we developed a parametric reconstruction method to a homogeneous, isotropic and spatially flat Friedmann-Robertson-Walker (FRW) cosmological model filled of a flui…
On the galactic rotation curves problem within an axisymmetric approach
Cesar Alvarez, Olindo Corradini, Alfredo Herrera-Aguilar +2
In U. Nucamendi et al. Phys. Rev. D63 (2001) 125016 and K. Lake, Phys. Rev. Lett. 92 (2004) 051101 it has been shown that galactic potentials can be kinematically linked to the obs…
Thick Brane Isotropization in a Generalized 5D Anisotropic Standing Wave Braneworld Model
Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +2
We study a smooth cosmological solution within a generalized 5D standing wave braneworld modeled by gravity and a phantom scalar field. In this model the 3-brane is anisotropically…
