Figure 1 (IMAGE) Tohoku University Caption Photon spectra produced by magnetic reconnection in the vicinity of the black hole . The left panel shows the case for M87 and the right for Sgr A*. HiZ-GUNDAM and FORCE are the planned X-ray satellites, whose sensitivities are shown in black dashed lines. The data points in the left panel are the observed photon spectrum during a quiescent state. The blue line with a shaded region in the right panel exhibits the photon spectrum of currently observed long-term flare. The future X-ray satellites can detect the signals by the magnetic reconnection in the vicinity of the black holes, which will unravel the plasma loading mechanism to the radio jets.
