Oral Presentation
Current Status and Future Plans for the Nobeyama Radio Observatory 45-m Telescope
Presenter: Rin Yamada (National Astronomical of Japan/Nobeyama Radio Observatory)
The Nobeyama 45-m radio telescope, located at 1,400 m in Nagano, Japan, has been a world-leading facility for millimeter-wave astronomy since 1982. Its large aperture provides high spatial resolution (~20″ at 110 GHz), while the four-beam FOREST receiver offers wide-area mapping capability across 70–110 GHz, and three legacy programs have been conducted (e.g., FUGIN; Umemoto et al. 2017). In addition to FOREST, the Z45 receiver enables magnetic-field studies via Zeeman polarimetry, and new instruments are underway: HINOTORI will provide simultaneous observations at 20, 40, and 86 GHz, and 7-BEE, a seven-beam successor to FOREST, is being prepared for open use. Observing time is offered internationally at 30,000 JPY hr⁻¹, without proposal review, and welcomes challenging science. The observatory also supports 11 ongoing university-led developments, from next-generation receiver prototypes to specialized systems for focused science. We present the current status of the Nobeyama 45-m telescope and discuss future directions for science and instrumentation.
