November 2021: Early Science papers released!
Seven Early Science papers have been released on arXiv, covering topics including:
- An overview of the Early Science results
- A description of the Pathfinder instrument
- The first-generation data analysis pipeline
- Power spectrum estimation from the first 13 months of observing
- Constraints on galaxy properties and forecasts for the 5-year dataset
- A first look at a continuum survey of the Galactic plane
- Prospects for future phases of the project targeting Reionization.
- Ways to account for line broadening in line intensity mapping forecasts
- The various voxel-level analyses possible when combining COMAP data with a Galaxy survey catalog
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!
We have deployed the receiver with two feeds operational and have obtained the first-light maps of Jupiter shown above.
