Characterization of sensitivity and responses of a 2-element prototype wavefront sensor for millimeter-wave adaptive optics attached to the Nobeyama 45 m telescope
Satoya Nakano, Yoichi Tamura, Akio Taniguchi +5
We report the results of the performance characterization of a prototype wavefront sensor for millimetric adaptive optics (MAO) installed on the Nobeyama 45 m radio telescope. MAO…
DESHIMA 2.0: development of an integrated superconducting spectrometer for science-grade astronomical observations
Akio Taniguchi, Tom J. L. C. Bakx, Jochem J. A. Baselmans +32
Integrated superconducting spectrometer (ISS) technology will enable ultra-wideband, integral-field spectroscopy for (sub)millimeter-wave astronomy, in particular, for uncovering t…
A data-scientific noise-removal method for efficient submillimeter spectroscopy with single-dish telescopes
Akio Taniguchi, Yoichi Tamura, Shiro Ikeda +2
For submillimeter spectroscopy with ground-based single-dish telescopes, removing noise contribution from the Earth's atmosphere and the instrument is essential. For this purpose,…
Wavefront sensor for millimeter/submillimeter-wave adaptive optics based on aperture-plane interferometry
Yoichi Tamura, Ryohei Kawabe, Yuhei Fukasaku +20
We present a concept of a millimeter wavefront sensor that allows real-time sensing of the surface of a ground-based millimeter/submillimeter telescope. It is becoming important fo…
Large format imaging spectrograph for the Large Submillimeter Telescope (LST)
K. Kohno, R. Kawabe, Y. Tamura +19
We present a conceptual study of a large format imaging spectrograph for the Large Submillimeter Telescope (LST) and the Atacama Large Aperture Submillimeter Telescope (AtLAST). Re…
The Atacama Large Aperture Submillimetre Telescope (AtLAST)
Pamela D. Klaassen, Tony Mroczkowski, Claudia Cicone +11
The coldest and densest structures of gas and dust in the Universe have unique spectral signatures across the (sub-)millimetre bands (~GHz). The current generation…
