Axion Helioscopes as Solar Thermometers
Sebastian Hoof, Joerg Jaeckel, Lennert J. Thormaehlen
Axions, if discovered, could serve as a powerful new messenger for studying astrophysical objects. In this study we show how the Sun's spatial and spectral "axion image" can be inv…
Probing the axion-nucleon coupling with the next generation of axion helioscopes
Luca Di Luzio, Javier Galan, Maurizio Giannotti +8
A finite axion-nucleon coupling, nearly unavoidable for QCD axions, leads to the production of axions via the thermal excitation and subsequent de-excitation of Fe-57 isotopes in t…
Quantifying uncertainties in the solar axion flux and their impact on determining axion model parameters
Sebastian Hoof, Joerg Jaeckel, Lennert J. Thormaehlen
We review the calculation of the solar axion flux from axion-photon and axion-electron interactions and discuss the size of various effects neglected in current calculations. For t…
Leading Logs in QCD Axion Effective Field Theory
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective fie…
Hidden Photon Dark Matter in the Light of XENON1T and Stellar Cooling
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The low-energy electronic recoil spectrum in XENON1T provides an intriguing hint for potential new physics. At the same time, observations of horizontal branch stars favor the exis…
Axions as a probe of solar metals
Joerg Jaeckel, Lennert J. Thormaehlen
If axions or axion-like particles exist and are detected, they will not only extend the standard model of particle physics but will also open a new way to probe their sources. Axio…
Distinguishing Axion Models with IAXO
Joerg Jaeckel, Lennert J. Thormaehlen
Helioscopes, such as the proposed International Axion Observatory (IAXO), have significant discovery potential for axions and axion-like particles. In this note, we argue that beyo…
