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…
Audible Axion Magnetogenesis: Linking Intergalactic Magnetic Fields and Gravitational Waves
Christopher Gerlach, Daniel Schmitt, Pedro Schwaller
Identifying dark matter candidates that simultaneously generate multiple observable cosmological signatures is a key goal in connecting particle physics with upcoming observations.…
Thermodynamical uncertainties for primordial black holes from cosmological phase transitions
Maciej Kierkla, Nicklas Ramberg, Philipp Schicho +1
Strongly supercooled first-order phase transitions have been proposed as a primordial black hole (PBH) production mechanism. While previous works rely on simplified models with lim…
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…
Impact of theoretical uncertainties on model parameter reconstruction from GW signals sourced by cosmological phase transitions
Marek Lewicki, Marco Merchand, Laura Sagunski +2
Different computational techniques for cosmological phase transition parameters can impact the Gravitational Wave (GW) spectra predicted in a given particle physics model. To scrut…
Binary systems in massive scalar-tensor theories: Next-to-leading order gravitational wave phase from effective field theory
Robin Fynn Diedrichs, Daniel Schmitt, Laura Sagunski
Neutron star binaries and their associated gravitational wave signal facilitate precision tests of General Relativity. Any deviation of the detected gravitational waveform from Gen…
Supercool exit: Gravitational waves from QCD-triggered conformal symmetry breaking
Laura Sagunski, Philipp Schicho, Daniel Schmitt
Classically conformal Standard Model extensions predict an intriguing thermal history of the early universe. In contrast to the common paradigm, the onset of the electroweak phase…
