Robustness of inflation to kinetic inhomogeneities
Matthew Elley, Josu C. Aurrekoetxea, Katy Clough +3
We investigate the effects of large inhomogeneities in both the inflaton field and its momentum. We find that in general, large kinetic perturbations reduce the number of e-folds o…
Spinning primordial black holes formed during a matter-dominated era
Eloy de Jong, Josu C. Aurrekoetxea, Eugene A. Lim +1
We study the formation of spinning primordial black holes during an early matter-dominated era. Using non-linear 3+1D general relativistic simulations, we compute the efficiency of…
Primordial black hole formation with full numerical relativity
Eloy de Jong, Josu C. Aurrekoetxea, Eugene A. Lim
We study the formation of black holes from subhorizon and superhorizon perturbations in a matter dominated universe with 3+1D numerical relativity simulations. We find that there a…
The Effects of Potential Shape on Inhomogeneous Inflation
Josu C. Aurrekoetxea, Katy Clough, Raphael Flauger +1
We study the robustness of single-field inflation against inhomogeneities. We derive a simple analytic criterion on the shape of the potential for successful inflation in the prese…
