ALMA observations of the magnetar SGR 1745-2900 exclude axion-photon couplings down to ~2e-13 GeV^-1 in the 0.55-0.62 meV mass range, reaching the QCD axion window under a dark-matter spike model.

Constraining meV Axion Dark Matter with ALMA Observations of the Galactic Center Magnetar SGR 1745-2900
