GRBoondi: A code for evolving Generalized Proca theories on arbitrary backgrounds

GRBoondi is a brand new numerical relativity code tailored to the study of generalized Proca fields in arbitrary spacetimes. This is a powerful new library that will enable the rapid study of any one of the generalized Proca theories.

Proca in an Expanding Universe

The superradiant growth of a massive vector field surrounding a rapidly spinning black hole in an expanding universe is studied, further elucidating the behavior of massive vector fields in our own universe.

Detecting Fundamental Vector Fields with LISA

Leveraging black hole collisions as cosmic-scale particle detectors allows us to study fundamental matter fields using astrophysical dynamics.

Gravitational Waves in Full, Non-Linear General Relativity

Asymptotic symmetries of spacetime place strong and interesting constraints on gravitational waveforms. This book provides an introduction to the necessary mathematics to understand gravitational waves in full, non-linear general relativity.

Black holes in f(Q) Gravity

Differential geometry allows for different, but equal, descriptions of gravity. Here we investigate black holes described not by curvature of spacetime, but by another mathematical property.

Positive energy warp drive from hidden geometric structures

Certain geometric structures lay at the heart of the most common model for warp drives, allowing for greater insight into the feasibility of human-created warp bubbles.
