Overview and design optimization of a custom hybrid X-ray telescope for the International Axion Observatory (IAXO)
Yue Yu, Jooyun Woo, Ipek Altunyurt +34
We present the design optimization for maximizing the effective area of a custom X-ray optic for the International Axion Observatory (IAXO) and BabyIAXO, including its novel hybrid…
NuSTAR as an Axion Helioscope: probing axion-nucleon and axion-electron couplings
Tiziano Zanzarella, Francisco R. Candón, Maurizio Giannotti +5
We investigate solar X-ray observations as a probe of axions and axion-like particles. These particles can be produced in the interior of the Sun via the conversion of thermal phot…
Stripped-Envelope Supernovae for QCD Axion Detection
Francisco R. Candón, Damiano F. G. Fiorillo, Ãngel Gil Muyor +3
QCD axions would be copiously produced in the proto-neutron star formed in a core-collapse supernova (SN). After escaping, they would convert into gamma rays in the Galactic magnet…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Probing the Axion-Nucleon Coupling with Supergiant Stars
Francisco R. Candón, Pablo Casaseca, Maurizio Giannotti +3
A finite axion-nucleon coupling enables the production of axions in stellar environments via the thermal excitation and subsequent de-excitation of the Fe isotope. Given its…
Small Progenitors, Large Couplings: Type Ic Supernova Constraints on Radiatively Decaying Particles
Francisco R. Candón, Francisco R. Candón, Damiano F. G. Fiorillo +3
Supernova (SN) 1987A provides classic bounds on gamma-ray flashes from the radiative decay of sub-GeV particles, but the latter may decay so rapidly as to be shielded by the stella…
