CONCERTO
(Carbon CII Line in Post-Reionization and Reionization Epoch)
(spectrometer aimed at mapping the [CII] line)
CONCERTO (loosely for
Carbon CII Line in Post-Reionization and Reionization Epoch)
is a spectrometer for intensity mapping of the redshifted
ionized carbon forbidden line [CII]
from the epoch of reionization and from subsequent star formation.
As of 4/2021, it is installed on the Atacama Pathfinder Experiment (APEX).
The spectral line is in the submillimeter range,
and the instrument will disperse wavelengths with
a Martin-Puplett interferometer
(type of adjustable Michelson interferometer)
and sense with KIDs, achieving spectral resolutions
down to 1 GHz and
angular resolutions down to 20 arcseconds.
A related effort is KISS (for KIDs Interferometer Spectrum Survey)
with an analogous instrument for a lower frequency range,
aiming to map Sunyaev-Zel'dovich effects. It is installed on one of the
two 2.25-m QUIJOTE telescopes
at Teide Observatory on the Canary Islands.
