Spinodal Gravitational Waves

Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +5

We uncover a new gravitational-wave production mechanism in cosmological, first-order, thermal phase transitions. These are usually assumed to proceed via the nucleation of bubbles…

Domain Collisions

Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +3

We use holography to study collisions of phase domains formed in a four-dimensional, strongly-coupled gauge theory with a first-order, thermal phase transition. We find three quali…

Gauge structure of the Einstein field equations in Bondi-like coordinates

Thanasis Giannakopoulos, Nigel T. Bishop, David Hilditch +2

The characteristic initial (boundary) value problem has numerous applications in general relativity (GR) involving numerical studies, and is often formulated using Bondi-like coord…

Instabilities of scalar fields around oscillating stars

Taishi Ikeda, Vitor Cardoso, Miguel Zilhão

The behavior of fundamental fields in strong gravity or nontrivial environments is important for our understanding of nature. This problem has interesting applications in the conte…

Bubble Wall Velocity from Holography

Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +3

Cosmological phase transitions proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the bubble…

Mass-ratio and Magnetic Flux-Dependence of Modulated Accretion from Circumbinary Disks

Scott C. Noble, Julian H. Krolik, Manuela Campanelli +4

Accreting supermassive binary black holes (SMBBHs) are potential multi-messenger sources because they emit both gravitational wave and electromagnetic (EM) radiation. Past work has…
