About the project

COMAP is the first dedicated large-scale intensity mapping experiment targeting redshifted CO line emission from distant galaxies. It will employ coherent receivers observing between 26 and 34 GHz, covering redshifts between 2.4 and 3.4 with the first CO transition line (115 GHz), and redshifts between 5.8 and 7.8 with the second CO transition line (230 GHz). The COMAP instrument is fielded on a 10-m telescope at Owens Valley Radio Observatory in California, USA. COMAP started taking pathfinder observations in 2018, and will during 2019 field all 19 pathfinder pixels.


The main goal is to map the 3D-distribution of galaxies in the early universe using redshifted CO line emission. A secondary objective is to understand spinning dust emission by making sensitive maps of the Milky Way between 26 and 34 GHz.


    The Norwegian participation in COMAP is funded by the Research Council of Norway through the ROMFORSK program.


    COMAP is a collaboration between Caltech, Stanford, JPL, Maryland, Miami, CITA, Manchester and Oslo.
