Green light for astronomers: DESHIMA 2.0 instrument now fully characterized

Researchers from SRON and TU Delft have published the reference framework for their DESHIMA 2.0 spectrometer on the ASTE telescope in Chile. Although it has been collecting data since 2023, this laboratory analysis provides the missing key. Astronomers can finally verify their raw observational data and turn it into concrete discoveries about the early universe.
