Comparing twist-free axisymmetric gravitational waves near the black hole threshold
Ananya Adhikari, Tomáš Ledvinka, Daniela Cors +4
The threshold of black hole formation in axisymmetric vacuum gravity is proving to be more complicated than had been anticipated but, following recent advances, a consensus between…

Boson star head-on collisions with constraint-violating and constraint-satisfying initial data
Florian Atteneder, Hannes R. Rüter, Daniela Cors +3
Simulations of binary collisions involving compact objects require initial data that satisfy the constraint equations of general relativity. For binary boson star simulations it is…

Boson stars in massless and massive scalar-tensor gravity
Tamara Evstafyeva, Roxana Rosca-Mead, Ulrich Sperhake +1
We study phenomenological features and stability of boson stars in massless and massive scalar-tensor theory of gravity with Damour-Esposito-Farese coupling. This coupling between…
