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…
Stochastic gravitational wave background from supernovae in massive scalar-tensor gravity
Roxana Rosca-Mead, Michalis Agathos, Christopher J. Moore +1
In massive scalar-tensor gravity, core-collapse supernovae are strong sources of scalar-polarized gravitational waves. These can be detectable out to large distance. The dispersive…
Structure of neutron stars in massive scalar-tensor gravity
Roxana Rosca-Mead, Christopher J. Moore, Ulrich Sperhake +2
We compute families of spherically symmetric neutron-star models in two-derivative scalar-tensor theories of gravity with a massive scalar field. The numerical approach we present…
Core collapse in massive scalar-tensor gravity
Roxana Rosca-Mead, Ulrich Sperhake, Christopher J. Moore +3
This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {\b…
Inverse-chirp signals and spontaneous scalarisation with self-interacting potentials in stellar collapse
Roxana Rosca-Mead, Christopher J Moore, Michalis Agathos +1
We study how the gravitational wave signal from stellar collapse in scalar-tensor gravity varies under the influence of scalar self-interaction. To this end, we extract the gravita…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
