The Deep Spectroscopic High-redshift Mapper (DESHIMA) is a new, wideband spectrometer for the Atacama Submillimeter Telescope Experiment (ASTE). By employing a novel integrated superconducting spectrometer design based on the microwave kinetic inductance detector (MKID) technology, DESHIMA can instantaneously cover a wide instantaneous bandwidth. The primary goal of DESHIMA is to rapidly measure the redshift of dusty star-forming galaxies in the early universe.

Back to the Atacama! DESHIMA 2.0 starts observing

We installed the “full” DESHIMA 2.0 on the ASTE telescope in the autumn of 2023, achieving first light on 26th October 2023 and accumulating over three weeks’ worth of data. Compared to the DESHIMA 1.0 prototype from 2017, DESHIMA 2.0 has a 4x wider instantaneous bandwidth (180 GHz vs. 45 GHz), better frequency resolution, and improved sensitivity. Twelve scientists and engineers from the Netherlands, Japan, and Sweden, alongside the ASTE staff, participated in the campaign. Our team is currently working on calibrating and processing the data. DESHIMA remains mounted on the telescope, waiting to resume observations in March 2024.


DESHIMA is developed by a collaboration of the following groups in the Netherlands and Japan.
