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 fielded all 19 pathfinder pixels in 2019.


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.


    From 2016-2019 the Norwegian participation in COMAP was funded by the Research Council of Norway through the ROMFORSK program. Now is it supported by an ERC Consolidator grant.


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