Dynamical attractors in contracting spacetimes dominated by kinetically coupled scalar fields
Anna Ijjas, Frans Pretorius, Paul J. Steinhardt +1
We present non-perturbative numerical relativity simulations of slowly contracting spacetimes in which the scalar field driving slow contraction is coupled to a second scalar field…
Can Thorne-ytkow Objects source GW190814-type events?
Ilias Cholis, Konstantinos Kritos, David Garfinkle
The LIGO-Virgo collaboration reported in their third run the coalescence event GW190814 involving a 2.6 object with a 23 black hole. In this letter we study…
A numerical stability analysis of mean curvature flow of noncompact hypersurfaces with Type-II curvature blowup
David Garfinkle, James Isenberg, Dan Knopf +1
We present a numerical study of the local stability of mean curvature flow of rotationally symmetric, complete noncompact hypersurfaces with Type-II curvature blowup. Our numerical…
