Axion-like particle (ALP) is a dark matter candidate predicted by certain extensions of the Standard Model. They are emitted in core-collapse supernovae (CCSNe) via the Primakoff process and undergo a conversion into gamma rays in the presence of an external magnetic field. We observe this effect through an enhanced gamma-ray flux from a CCSN. The study of these spectral irregularities in gamma-ray signals allows for a search of traces of ALPs, as well as determination of constraints on photon-ALP coupling. In this project, we search for these irregularities in the extragalactic core-collapse supernovae with spectral peaks at around ~60 MeV, corresponding to the peak of ALP-induced gamma-ray bursts, thus considering the data both from the upper energy limit of the Fermi-GBM as well as lower energy limit of the LAT instrument.
