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.…
Superhorizon Isocurvature as a Window into Dark Matter Production
Christopher Gerlach, Wolfram Ratzinger, Pedro Schwaller
In the presence of primordial isocurvature perturbations, for example in a separate dark radiation sector, the superhorizon evolution of curvature perturbations becomes nontrivial.…
Generalized neutrino isocurvature
Christopher Gerlach, Wolfram Ratzinger, Pedro Schwaller
Searches for neutrino isocurvature usually constrain a specific linear combination of isocurvature perturbations. In this work, we discuss realistic cosmological scenarios giving r…
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…
