概要 We present upper limits in the hard X-ray and gamma-ray bands at the time of the Laser Interferometer Gravitational-wave Observatory (LIGO) gravitational-wave event GW151226 derived from the CALorimetric Electron Telescope (CALET) observation. We place a 90% upper limit of 2 × 10^-7 erg cm^-2 s^-1 in the 1-100 GeV band where CAL reaches 15% of the integrated LIGO probability (~1.1 sr). The CGBM 7σ upper limits are 1.0x10^-6 erg cm^-2 s^-1 (7-500 keV) and 1.8x10^-6 erg cm^-2 s^-1 (50-1000 keV) for a 1 s exposure. Those upper limits correspond to the luminosity of 3-5 x 10^49 erg s^1, which is significantly lower than typical short GRBs.
