July 2022: Early Science papers published!

Our seven Early Science papers have been published in The Astrophysical Journal, where they are the subject of a special Focus Issue.

November 2021: Early Science papers released!

Seven Early Science papers have been released on arXiv, covering topics including:

Two companion papers describe:

June 2019: Science observing has begun!

COMAP's Phase I observing campaign has begun. We are now taking science-quality data with the receiver. The full campaign is two years long, but an interim analysis will be performed on the first six months of data.

COMAP @ OVRO Open House 2019

About 250 people attended this year's Open House at the Owens Valley Radio Observatory. David Woody gave tour groups a talk at the COMAP antenna (see photo) while, in the control building, Kieran Cleary explained the aims of the experiment.

November 2018: Commissioning has begun with the full 19-pixel system!

The full 19-pixel receiver has been fielded and commissioning observations have begun. The full digital backend is in place and we can now process the full 8 GHz bandwidth from all 19 pixels. We are refining our scanning strategy and testing improvements to the receiver's polarizers.

August 2018: 7-pixel system installed!

We have increased the number of pixels to 7 and are taking test data. The figure shows test data taken one of COMAP’s main science fields, made using 16 hours of commissioning data in 8 GHz of bandwidth from 5 pixels. Units of the color scale are μK. The map is largely consistent with instrumental white noise, with a total rms sensitivity of ∼ 100 μK.

April 2018: First light with 2-pixel system!

Maps of Jupiter taken with the two-pixel system

We have deployed the receiver with two feeds operational and have obtained the first-light maps of Jupiter shown above.
