(CO Mapping Array Pathfinder)
(high frequency radio telescope to map CO)
COMAP (for CO Mapping Array Pathfinder)
is an intensity-mapping survey
to detect high redshift (z)
carbon monoxide looking for the CO(1-0) emission line
over the z range of 2.4-to-3.8
and the CO(2-1) line over the z range of 5.8-to-7.9.
Observations are in the 26-34 GHz range,
where these spectral lines fall given the redshift.
A challenge is separating this data from the foreground
EMR that falls within this frequency range.
The first phase is in operation: an imaging spectrometer on a
10-meter radio telescope with a 19-pixel receiver, located at
Owens Valley Radio Observatory. A second phase of five such telescopes is planned.
These are part of a pathfinder project for a more ambitious
plan to map CO during the epoch of reionization.
Current emphases is on the lower redshifts and developing techniques.
COMAP appears to be the present form of the "Carbon Monoxide Mapping Array (COMA)" plan,
its name suggesting it is a preliminary version.
