AXIONLIKE PARTICLES (ALPS) ARE WELL MOTIVATED DARK-MATTER (DM) CANDIDATES THAT WOULD BE COPIOUSLY PRODUCED DURING A CORE-COLLAPSE SUPERNOVA (SN). THEY WOULD SUBSEQUENTLY DECAY OR OSCILLATE INTO GAMMA RAYS INDUCING A GAMMA-RAY BURST LASTING TENS OF SECONDS THAT WOULD ARRIVE SIMULTANEOUSLY WITH THE SN NEUTRINOS. WE PROPOSE A NOVEL SEARCH FOR SUCH A SIGNAL FROM EXTRAGALACTIC SNE USING DATA COLLECTED WITH THE GAMMA-RAY BURST MONITOR AND THE LARGE AREA TELESCOPE ON BOARD THE FERMI SATELLITE. AS NEUTRINO DETECTORS LACK THE SENSITIVITY TO DETECT NEUTRINOS FROM SUCH EVENTS THE SN EXPLOSION TIMES WILL BE ESTIMATED USING OPTICAL LIGHT CURVES. BY COMBINING RESULTS FOR DOZENS OF SNE THE PROPOSED RESEARCH WILL OPEN A NEW POSSIBILITY IN THE SEARCH FOR ALP DM.
