Surfin' pp-waves with Good Vibrations: Causality in the presence of stacked shockwaves
Calvin Y. -R. Chen, Claudia de Rham, Aoibheann Margalit +1
Relativistic causality constrains the -matrix both through its analyticity, and by imposing lower bounds on the scattering time delay. These bounds are easiest to determine for…
A cautionary case of casual causality
Calvin Y. -R. Chen, Claudia de Rham, Aoibheann Margalit +1
We distinguish between the notions of asymptotic causality and infrared causality for gravitational effective field theories, and show that the latter gives constraints consistent…
Phase decoherence of gravitational wave backgrounds
Aoibheann Margalit, Carlo R. Contaldi, Mauro Pieroni
Metric perturbations affect the phase of gravitational waves as they propagate through the inhomogeneous universe. This effect causes Stochastic Gravitational Wave Backgrounds (SGW…
Massive vector fields in Kerr--Newman and Kerr--Sen black hole spacetimes
Ramiro Cayuso, Oscar J. C. Dias, Finnian Gray +5
The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein--Maxwell gravity (the Kerr--Newman solution)…
Principal Tensor Strikes Again: Separability of Vector Equations with Torsion
Ramiro Cayuso, Finnian Gray, David Kubiznak +3
Many black hole spacetimes with a 3-form field exhibit a hidden symmetry encoded in a torsion generalization of the principal Killing--Yano tensor. This tensor determines basic pro…
