of detecting axions using a strong magnetic field that need be no stronger than that produced in an MRI scanning machine. It would show variation, a slight wavering, that is linked to the mass of the axion. The experiment is now being implemented by experimentalists at the university. In 2022 the polarized light measurements of Messier 87* by the EHT were used to constrain the mass of the axion assuming that hypothetical clouds of axions could form around a black hole rejecting the ~ eV/c^2 range of mass values. Searches for resonance effects Resonance effects may be evident in Josephson junctions from a supposed high flux of axions from the galactic halo with mass of 110 µeV and density compared to the implied dark matter density , indicating said axions would not have enough mass to be the sole component of dark matter. The ORGAN experiment plans to conduct a direct test of this result via the haloscope method. Dark matter recoil searches Dark matter cryogenic detectors have searched for electron recoils that would indicate axions. CDMS published in 2009 and EDELWEISS set coupling and mass limits in 2013. UORE and XMASS also set limits on solar axions in 2013. XENON100 used a 225 day run to set the best coupling limits to date and exclude some parameters. Nuclear spin precession While Schiff's theorem states that a static nuclear electric dipole moment (EDM) does not produce atomic and molecular EDMs, the axion induces an oscillating nuclear EDM which oscillates at the Larmor frequency. If this nuclear EDM oscillation frequency is in resonance with an external electric field, a precession in the nuclear spin rotation occurs. This precession can be measured using precession magnetometry and if detected, would be evidence for Axions. An experiment using this technique is the Cosmic Axion Spin Precession Experiment (CASPEr). Searches at Particle Colliders Axions can also be produced at colliders, in particular in electron positron collisions as well as in ultra-peripheral heavy ion collisions at the LHC, reinterpreting the light-by-light scattering process. Those searches are sensitive for rather large axion masses between 100 MeV/c^2 and hundreds of GeV/c^2. Assuming a coupling of axions to the Higgs Boson, searches for anomalous Higgs boson decays into two axions can provide even stronger limits. Possible detections It was reported in 2014 that evidence for axions may have been detected as a seasonal variation in observed X-ray emission that
