abstract
I present the first constraints on QCD axion dark matter using measurements from the James Webb Space Telescope. By utilizing publicly available MIRI and NIRSpec blank-sky observations, originally collected for sky subtraction purposes, I derive strong limits on the axion-photon coupling constant $g_{a \gamma \gamma}$ in the mass range 0.1-4 eV. These constraints improve upon previous studies by more than two orders of magnitude for a range of masses. This analysis underscores the potential of blank-sky observations as a powerful tool for constraining dark matter models and demonstrates how astrophysical missions can be repurposed for particle physics research.

Axion dark matter induces a resonantly enhanced pressure between graphene plates whose peaks and widths are controlled by graphene conductivity, chemical potential and dissipation, yielding projected sensitivities competitive in optimistic regimes.
Limits on axion-like particles from photon-coupling searches are recast as constraints on massive graviton-like particles across lab, astrophysical, and cosmological experiments using analogous Primakoff and Gertsenshtein conversion mechanisms.
Axion-like particles in the trapped misalignment mechanism produce observable gravitational waves while generating intergalactic magnetic fields that exceed blazar lower bounds in the parameter space promising for gravitational wave detection.
Cosmic muons produce synchrotron radiation that is not a dominant background for current high-Q axion searches but poses a risk for future broadband detectors lacking sufficient energy resolution.
A comprehensive formulation is given for the angular power spectrum of photons from dark matter annihilation or decay, stressing that detector energy resolution is essential for accurate evaluation of line photon signals.
