Query: Detection of the thermal component in GRB 160107A   We present the detection of a blackbody component in GRB 160107A emission by
using the combined spectral data of the CALET Gamma-ray Burst Monitor (CGBM)
and the MAXI Gas Slit Camera (GSC). The MAXI/GSC detected the emission $\sim$45
s prior to the main burst episode observed by the CGBM. The MAXI/GSC and the
CGBM spectrum of this prior emission period is well fit by a blackbody with the
temperature of $1.0^{+0.3}_{-0.2}$ keV plus a power-law with the photon index
of $-1.6 \pm 0.3$. We discuss the radius to the photospheric emission and the
main burst emission based on the observational properties. We stress the
importance of the coordinated observations via various instruments collecting
the high quality data over a broad energy coverage in order to understand the
GRB prompt emission mechanism.
