On the Schwinger effect during axion inflation
Richard von Eckardstein, Kai Schmitz, Oleksandr Sobol
Pair-creation of charged particles in a strong gauge-field background - the renowned Schwinger effect - can strongly alter the efficiency of gauge-field production during axion inf…
The NANOGrav 15 yr Data Set: Running of the Spectral Index
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102
The NANOGrav 15-year data provides compelling evidence for a stochastic gravitational-wave (GW) background at nanohertz frequencies. The simplest model-independent approach to char…
Scalar perturbations from inflation in the presence of gauge fields
R. Durrer, R. von Eckardstein, Deepen Garg +3
We study how Abelian-gauge-field production during inflation affects scalar perturbations in the case when the gauge field interacts with the inflaton directly (by means of generic…
Axion inflation in the strong-backreaction regime: decay of the Anber-Sorbo solution
Richard von Eckardstein, Marco Peloso, Kai Schmitz +2
Axion inflation coupled to Abelian gauge fields via a Chern-Simons-like term of the form represents an attractive inflationary model with a rich phenomenology, includ…
PTArcade
Andrea Mitridate, David Wright, Richard von Eckardstein +5
This is a lightweight manual for PTArcade, a wrapper of ENTERPRISE and ceffyl that allows for easy implementation of new-physics searches in PTA data. In this manual, we describe h…
MSSM-inflation revisited: Towards a coherent description of high-energy physics and cosmology
Gilles Weymann-Despres, Sophie Henrot-Versillé, Gilbert Moultaka +3
The aim of this paper is to highlight the challenges and potential gains surrounding a coherent description of physics from the high-energy scales of inflation down to the lower en…
