We will report the first-look results of our ALMA Large Program; eDisk, toward the Class 0 protostar IRAS 16544-1604 in Ophiuchus. The 1.3-mm dust-continuum emission in IRAS 16544-1604 shows an elongated dusty disk feature close to edge-on (i ~ 73 degree) with a disk radius of ~ 30 au. The intensity profiles of the dust continuum emission both along the minor and major axes exhibit the asymmetric distribution. The asymmetry along the minor axis reflects the dust flaring traced by the optically-thick 1.3-mm emission, whereas that along the major axis represents a real non-axisymmetric structure in the disk. The high velocity C18O (J=2-1) emission is distributed along the major axis of the dusty disk, and its velocity structure can be explained by the Keplerian rotation with a central protostellar mass of 0.14 solar mass. Furthermore, we found three elongated structures with a thousand au on the northern side. The spatial/velocity structures of these structures can be interpreted as accreting and rotating gas streamers. We will summarize these results and discuss their implications in our poster.
