Braneworld Black Holes in Cosmology and Astrophysics
The braneworld description of our universe entails a large extra dimension and a fundamental scale of gravity that might be lower by several orders of magnitude compared to the Planck scale. An interesting consequence of the braneworld scenario is in the nature of spherically symmetric vacuum solutions to the brane gravitational field equations which could represent black holes with properties ...
متن کاملOn the existence and dynamics of braneworld black holes
Based on holographic arguments Tanaka and Emparan et al have claimed that large localized static black holes do not exist in the one-brane Randall-Sundrum model. If such black holes are time-dependent as they propose, there are potentially significant phenomenological and theoretical consequences. We revisit the issue, arguing that their reasoning does not take into account the strongly coupled...
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...
متن کاملCharged black holes from near extremal black holes
We recover the properties of a wide class of far from extremal charged black branes from properties of near extremal black branes, generalizing the results of Danielsson, Guijosa and Kruczenski.
