Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions
Maciej Kierkla, Marek Lewicki, Philipp Schicho +2
Future interferometers may detect a gravitational-wave (GW) signal from a cosmological first-order phase transition. Reconstructing the underlying particle-physics model from such…

Supercooled Audible Axions
Christopher Gerlach, Daniel Schmitt, Pedro Schwaller
In the audible axion mechanism, axion-like particles source primordial gravitational waves via their coupling to a dark Abelian gauge field. The original setup, however, relies on…

QCD-sourced tachyonic phase transition in a supercooled Universe
Daniel Schmitt, Laura Sagunski
We propose a novel gravitational wave production mechanism in the context of quasi-conformal Standard Model extensions, which provide a way to dynamically generate the electroweak…
