GRTresna: An open-source code to solve the initial data constraints in numerical relativity
Josu C. Aurrekoetxea, Sam E. Brady, Llibert Aresté-Saló +11
GRTresna is a multigrid solver designed to solve the constraint equations for the initial data required in numerical relativity simulations. In particular, it is focussed on scenar…
Primordial black hole formation processes with full numerical relativity
Eloy de Jong
See thesis for complete abstract. Primordial black holes (PBHs) can form in the early universe, and there are several mass windows in which their abundance today may be large enoug…
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…
Electromagnetic instability of compact axion stars
Liina M. Chung-Jukko, Eugene A. Lim, David J. E. Marsh +3
If the dark matter is composed of axions, then axion stars are expected to be abundant in the Universe. We demonstrate in fully non-linear (3+1) numerical relativity the instabilit…
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…
