Slow-roll parameters in braneworld cosmologies
We present a general slow-roll formalism within braneworld-motivated cosmologies with nonstandard effective Friedmann equations. Full towers of parameters involving either the inflaton potential or the Hubble parameter are constructed and the dynamics of non-tachyonic and tachyonic fields are considered in detail; exact cosmological solutions and the inflationary attractor condition are provide...
متن کاملEternally accelerating spacelike braneworld cosmologies
We construct an eternally inflating spacelike brane world model. If the space dimension of the brane is three (SM2) or six (SM5) for M theory or four (SD3) for superstring theory, a time-dependent n-form field would supply a constant energy density and cause exponentially expansion of the spacelike brane. In these cases, the hyperbolic space perpendicular to the brane would keep its scale facto...
متن کاملObservational constraints on phantom-like braneworld cosmologies
We investigate a simple braneworld model in which the universe contains only cold dark matter and a cosmological constant, but the effective dark energy is phantom-like because of extra-dimensional gravity effects. Modified gravity screens the cosmological constant Λ, allowing for a larger Λ. In practice, observations do not favour any significant screening. We use supernova data, the cosmic mi...
متن کاملPrimordial black holes in braneworld cosmologies: Accretion after formation
We recently studied the formation and evaporation of primordial black holes in a simple braneworld cosmology, namely the Randall-Sundrum type II cosmology. Here we study the effect of accretion from the cosmological background onto the black holes after formation. While it is generally believed that in the standard cosmology such accretion is of negligible importance, we find that during the hi...
متن کاملPrimordial black holes in braneworld cosmologies: Astrophysical constraints
In two recent papers we explored the modifications to primordial black hole physics when one moves to the simplest braneworld model, Randall-Sundrum type II. Both the evaporation law and the cosmological evolution of the population can be modified, and additionally accretion of energy from the background can be dominant over evaporation at high energies. In this paper we present a detailed stud...
