      abstract = {Dark matter particles with a mass around 1 eV can decay  into near-infrared photons. Utilizing available public  blank sky observations from the NIRSpec IFU on the James  Webb Space Telescope (JWST), we search for a narrow  emission line due to decaying dark matter and derive  leading constraints in the mass range 0.8–3 eV on the decay  rate to photons, and more specifically, on the axion-photon  coupling for the case of axionlike particles. We exclude $𝜏  <3.5 ×10^{26}  s$ at $𝑚_{DM}≃0.8  eV$ and, in the case of  axions, $𝑔_{𝑎⁢𝛾⁢𝛾}>1.3×10^{−11}  GeV^{−1}$ for  $𝑚_𝑎≃2.2  eV$. Our results do not rely on dedicated  observations, rather we use blank sky observations intended  for sky subtraction, and thus our reach may be  automatically strengthened as JWST continues to observe.},
