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…
Cooling binary neutron star remnants via nucleon-nucleon-axion bremsstrahlung
Tim Dietrich, Katy Clough
The QCD axion is a hypothetical particle motivated by the Strong CP problem of particle physics. One of the primary ways in which its existence can be inferred is via its function…
The Fate of Dense Scalar Stars
Francesco Muia, Michele Cicoli, Katy Clough +3
Long-lived pseudo-solitonic objects, known as oscillons/oscillatons, which we collectively call real scalar stars, are ubiquitous in early Universe cosmology of scalar field theori…
Saving the universe with finite volume effects
Jean Alexandre, Katy Clough
Setting aside anthropic arguments, there is no reason why the universe should initially favour a net expanding phase rather than one experiencing a net contraction. However, a coll…
On the growth of massive scalar hair around a Schwarzschild black hole
Katy Clough, Pedro G. Ferreira, Macarena Lagos
Through numerical simulations of a minimally coupled massive Klein-Gordon scalar field, we show that it is possible to grow hair on a Schwarzschild black hole if one assumes an ini…
