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…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
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…
Black hole formation from axion stars
Thomas Helfer, David J. E. Marsh, Katy Clough +3
The classical equations of motion for an axion with potential possess quasi-stable, localized, oscillating solutions, which we refer to as "axion…
