Complete classification of Friedmann-Lemaître-Robertson-Walker solutions with linear equation of state: parallelly propagated curvature singularities for general geodesics
Tomohiro Harada, Takahisa Igata, Takuma Sato +1
We completely classify the Friedmann-Lemaître-Robertson-Walker solutions with spatial curvature for perfect fluids with linear equation of state , where and $…
Self-complete and GUP-Modified Charged and Spinning Black Holes
Bernard Carr, Heather Mentzer, Jonas Mureika +1
We explore some implications of our previous proposal, motivated in part by the Generalised Uncertainty Principle (GUP) and the possibility that black holes have quantum mechanical…
Primordial black holes in a dimensionally reduced universe
Athanasios G. Tzikas, Piero Nicolini, Jonas Mureika +1
We investigate the spontaneous creation of primordial black holes in a lower-dimensional expanding early universe. We use the no-boundary proposal to construct instanton solutions…
Does Compton/Schwarzschild duality in higher dimensions exclude TeV quantum gravity?
Matthew J. Lake, Bernard Carr
In three spatial dimensions, the Compton wavelength ) and Schwarzschild radius ) are dual under the transformation , w…
Complete conformal classification of the Friedmann-Lemaitre-Robertson-Walker solutions with a linear equation of state
Tomohiro Harada, B. J. Carr, Takahisa Igata
We completely classify Friedmann-Lemaître-Robertson-Walker solutions with spatial curvature and equation of state , according to their conformal structure, singul…
Black holes as echoes of previous cosmic cycles
Bernard Carr, Timothy Clifton, Alan Coley
The existence of exact solutions which represent a lattice of black holes at a scalar-field-dominated cosmological bounce suggests that black holes could persist through successive…
