We built a Ka-band dual-circular-polarization low-noise receiver for the Misasa 54 m parabola antenna in Misasa, Japan. The antenna is designed to be combined with a transmitter and receiver system at the X band (around 8 GHz) and simultaneously w...
We present here the East Asia to Italy Nearly Global VLBI (EATING VLBI) project. How this project started and the evolution of the international collaboration between Korean, Japanese, and Italian researchers to study compact sources with VLBI obs...

Abstract
We present a detection of a bright burst from the fast radio burst (FRB) 20201124A, which is one of the most active repeating FRBs, based on S-band observations with the 64 m radio telescope at the Usuda Deep Space Center/JAXA. This is ...

We conducted observations and analyses of the molecular cloud, N4, which is located at similar to 40 pc from SS 433 and the same line of sight as that of the radio shell, in (CO)-C-12(J = 1-0), (CO)-C-12(J = 3-2), (CO)-C-13(J = 3-2), and grand-sta...

We conducted radio astronomy missions from space. We often use parabola antenna for radio telescopes. Most of radio telescopes are built on ground, but we need space observation for precise measurements or for getting longer baselines than the Ear...
