Imaging Super-Massive Black Hole with International Millimeter -Wave VLBI Observations
The Event Horizon Telescope (EHT) is a global mm/sub-mm VLBI array to directly observe the shadow of super-massive black holes. The EHT has been promoted by world-wide collaboration, and in April 2017 the first EHT observations including ALMA will be conducted with an expectation that structures in the vicinity of the event horizons will be revealed particularly toward the target sources Sgr A* and M87. In this talk, I will summarize the current status of EHT and also science results obtained so far. Also, I will introduce our new imaging technic based-on "sparse modeling", which aims at obtaining better resolution in imaging black holes, and discuss the future prospect of the science with the EHT.
