Description
GRB 241105A challenges traditional GRB classification, exhibiting properties at the boundary between short and long bursts. Its prompt emission—an initial hard spike with weaker extended emission—was detected by Fermi-GBM, Swift-BAT, and Konus-Wind. Spectral analysis using Power-Law, Comptonized, and Band function models, along with classification metrics such as spectral lag, hardness ratio, and machine learning techniques (PCA-UMAP), suggests an ambiguous nature. JWST photometry and Prospector SED fitting reveal a massive, low-metallicity, star-forming host. By analyzing its multi-wavelength behavior and searching for supernova signatures, we assess whether GRB 241105A represents a high-redshift compact binary merger or a short-duration collapsar, providing key insights into GRB progenitors and heavy-element enrichment.
