Development of the Phase-up Technology of the Radio Telescopes: 6.7 GHz Methanol Maser Observations with Phased Hitachi 32 m and Takahagi 32 m Radio …

For the sake of high-sensitivity 6.7 GHz methanol maser observations, we developed a new
technology for coherently combining the two signals from the Hitachi 32 m radio telescope
and the Takahagi 32 m radio telescope of the Japanese Very long baseline interferometer
Network (JVN), where the two telescopes were separated by about 260 m. After the two
telescopes were phased as a twofold larger single telescope, the mean signal-to-noise ratio
(S/N) of the 6.7 GHz methanol masers observed by the phased telescopes was improved to …
