Researchers in Japan and the Netherlands jointly developed an originative radio receiver DESHIMA (Deep Spectroscopic High-redshift Mapper) and successfully obtained the first spectra and images with it. Combining the ability to detect a wide frequency range of cosmic radio waves and to disperse them into different frequencies, DESHIMA demonstrated its unique power to efficiently measure the distances to the remotest objects as well as to map the distributions of various molecules in nearby cosmic clouds.

This research result is published as A. Endo et al. “First light demonstration of the integrated superconducting spectrometer” in Nature Astronomy on August 5, 2019.
