Hair is complicated: Gravitational waves from stable and unstable boson-star mergers
Bo-Xuan Ge, Eugene A. Lim, Ulrich Sperhake +5
We explore the gravitational-wave emission from head-on collisions of equal-mass solitonic boson-star binaries from simulations spanning a two-dimensional parameter space, consisti…
Cosmology using numerical relativity
Josu C. Aurrekoetxea, Katy Clough, Eugene A. Lim
This review is an up-to-date account of the use of numerical relativity to study dynamical, strong-gravity environments in a cosmological context. First, we provide a gentle introd…
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…
Multimessenger signals from compact axion star mergers
Liina Chung-Jukko, Eugene A. Lim, David J. E. Marsh
Axion dark matter can form stable, self-gravitating, and coherent configurations known as axion stars, which are rendered unstable above a critical mass by the Chern-Simons couplin…
