Axion Inflation: Perturbative control in the strong backreaction regime
Valerie Domcke, Alexandros Papageorgiou, Marco Peloso +1
We study the strong backreaction regime in axion inflation, in which the friction from Abelian gauge fields generated via the pseudo-scalar interaction $\fracβ{4 M_p} ÏF {\tilde…
Halbach Magnetic Weber Bars
Valerie Domcke, Itay M. Bloch
Magnetic Weber Bars have been proposed to search for gravitational waves in the kHz to GHz regime by exploiting the mechanical deformation of a large magnet induced by a gravitatio…
From S2 to LISA: Astrometric Bounds on Extreme-Mass-Ratio Inspirals and Bursts
Andrea Caputo, Valerie Domcke
The paper uses precise astrometric measurements of the star S2 near the Galactic centre to constrain the number of stellar‑mass black holes and estimate the rates of extreme‑mass‑r…
High-Frequency Gravitational Wave Constraints from Precision Spectroscopy
Dmitry Budker, Valerie Domcke, Joachim Kopp +1
The authors use precision laser spectroscopy to search for high‑frequency gravitational waves by detecting frequency modulations of photons in optical cavities, setting new limits…
The decay rate of metastable cosmic strings beyond the thin-string approximation
Valerie Domcke, Yu Hamada
In the context of grand unified theories, any cosmic strings present in the post-inflationary universe are likely to be metastable, with a decay rate set by the spontaneous creatio…
Challenges and Opportunities of Gravitational Wave Searches above 10 kHz
Nancy Aggarwal, Odylio D. Aguiar, Diego Blas +34
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
