Extended Data Fig. 6: X-ray afterglow of GRB 200826A.
From: A peculiarly short-duration gamma-ray burst from massive star core collapse
X-ray afterglow of GRB 200826A. Black points represents the observed X-ray flux in 0.3-10 keV. The solid orange line shows the broken power-law fitting with slopes α = -1.41\({}_{-0.12}^{+0.24}\), β= -0.43\({}_{-0.22}^{+0.17}\) and a break at tb = \(1.5{1}_{-0.30}^{+0.31}\times 1{0}^{5}\) s. The dashed blue line represents the magnetar spin-down energy injection model parameterized by Lsd = L0(1+t/τ)−2 with L0 = 1044.9ergs−1 and τ = 1.0 × 106s. All error bars represent 1-σ uncertainties. The upper limit is at the 3-σ level.
