Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies
N. Aggarwal, O. D. Aguiar, A. Bauswein +22
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…
Wash-In Leptogenesis
Valerie Domcke, Kohei Kamada, Kyohei Mukaida +2
We present a leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino masses as low as a few 100 TeV. This mechanism, wh…
MeV-scale Seesaw and Leptogenesis
Valerie Domcke, Marco Drewes, Marco Hufnagel +1
We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly const…
From NANOGrav to LIGO with metastable cosmic strings
Wilfried Buchmuller, Valerie Domcke, Kai Schmitz
We interpret the recent NANOGrav results in terms of a stochastic gravitational wave background from metastable cosmic strings. The observed amplitude of a stochastic signal can be…
Spontaneous Baryogenesis from Axions with Generic Couplings
Valerie Domcke, Yohei Ema, Kyohei Mukaida +1
Axion-like particles can source the baryon asymmetry of our Universe through spontaneous baryogenesis. Here we clarify that this is a generic outcome for essentially any coupling o…
Potential of radio telescopes as high-frequency gravitational wave detectors
Valerie Domcke, Camilo Garcia-Cely
In the presence of magnetic fields, gravitational waves are converted into photons and vice versa. We demonstrate that this conversion leads to a distortion of the cosmic microwave…
Deformation of the gravitational wave spectrum by density perturbations
Valerie Domcke, Ryusuke Jinno, Henrique Rubira
We study the effect of primordial scalar curvature perturbations on the propagation of gravitational waves over cosmic distances. We point out that such curvature perturbations def…
Resonant backreaction in axion inflation
Valerie Domcke, Veronica Guidetti, Yvette Welling +1
Axion inflation entails a coupling of the inflaton field to gauge fields through the Chern-Simons term. This results in a strong gauge field production during inflation, which back…
