  "abstract": "We show that the very recent detection of the gamma ray burst GRB221009A by the LHAASO experiment -- with its very-high-energy tail extending up to 18 TeV -- provides a hint at the existence of axion-like-particles with mass ${\\cal O} (10^{-10}) \\, {\\rm eV}$ and two-photon coupling ${\\cal O} (10^{-11}) \\, {\\rm GeV}^{- 1}$.",
