Getting More Out of Black Hole Superradiance: a Statistically Rigorous Approach to Ultralight Boson Constraints from Black Hole Spin Measurements
Sebastian Hoof, David J. E. Marsh, Júlia Sisk-Reynés +2
Black hole (BH) superradiance can provide strong constraints on the properties of ultralight bosons (ULBs). While most of the previous work has focused on the theoretical predictio…
Catalogues of Cosmologically Self-Consistent Hadronic QCD Axion Models
Luca Di Luzio, Sebastian Hoof, Coenraad Marinissen +1
We extend the catalogue of "phenomenologically preferred" hadronic axion models to include heavy fermion representations associated with higher-dimensional decay operators. The lat…
The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics
A. Arcusa, S. Ahyoune, K. Altenmuller +120
The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…
Ultimate light-shining-through-a-wall experiments to establish QCD axions as the dominant form of dark matter
Sebastian Hoof, Joerg Jaeckel, Giuseppe Lucente
Establishing the axion as the dark matter (DM) particle after a haloscope discovery typically requires follow-up experiments to break the degeneracy between the axion's coupling to…
An accurate solar axions ray-tracing response of BabyIAXO
S. Ahyoune, K. Altenmueller, I. Antolin +124
BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion heliosc…
