Outline of Final Research Achievements

Nasu telescope array is a direct imaging device in which the image of the radio source can be obtained in real-time. Angular resolution of the telescope is given by the total length of the array while the field of view is determined by the scale of the single dish. Our telescope has an angular resolution of 0.1 degrees and a field view of 0.8 degrees. By applying the new analysis method developed in this study, we can obtain high sensitive image of the radio sources. Thus, we could observe radio outbursts from V404 Cyg in 2015 and radio flares from Cyg X-3 in 2017. Both were very important events in the recent radio astronomy.
