Time-integrated νF_ν spectrum of GRB 220107A (episode 1; T₀ − 2 to T₀ + 38 s) fit with the cutoff power law plus blackbody (CPL+BB) model using Fermi/GBM data. The red curve shows the cutoff power law component, the blue curve shows the blackbody emission, and the green curve represents the total model. The shaded gray regions denote the 1σ uncertainties of each spectral component. The fit suggests a thermal blackbody component at kT ∼ 14 keV in addition to the nonthermal CPL continuum, which significantly improves the fit relative to purely nonthermal models.
