Bounds on neutrino-scalar nonstandard interactions from big bang nucleosynthesis
Jorge Venzor, Abdel Pérez-Lorenzana, Josue De-Santiago
Coherent forward scattering processes by neutrino-scalar nonstandard interactions (SNSI) induce an effective neutrino mass. In the Early Universe, a large neutrino effective mass r…
Relativistic and non-Gaussianity contributions to the one-loop power spectrum
Rebeca Martinez-Carrillo, Josue De-Santiago, Juan Carlos Hidalgo +1
We compute the one-loop density power spectrum including Newtonian and relativistic contributions, as well as the primordial non-Gaussianity contributions from and $g_…
Nonlinear evolution of initially biased tracers in modified gravity
Alejandro Aviles, Mario Alberto Rodriguez-Meza, Josue De-Santiago +1
In this work we extend the perturbation theory for modified gravity (MG) in two main aspects. First, the construction of matter overdensities from Lagrangian displacement fields is…
Cosmological constraints on a decomposed Chaplygin gas
Yuting Wang, David Wands, Lixin Xu +2
Any unified dark matter cosmology can be decomposed into dark matter interacting with vacuum energy, without introducing any additional degrees of freedom. We present observational…
Generalizing a Unified Model of Dark Matter, Dark Energy, and Inflation with Non Canonical Kinetic Term
Josue De-Santiago, Jorge L. Cervantes-Cota
We study a unification model for dark energy, dark matter, and inflation with a single scalar field with non canonical kinetic term. In this model the kinetic term of the Lagrangia…
