S.; Padmanabhan, Hamsa; Pearson, Timothy J.; Rennie, Thomas J.; Woody, David P. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present the power spectrum methodology used for the first-season COMAP analysis, and assess the quality of the current data set. The main results are derived through the Feed–Feed Pseudo-Cross-Spectrum (FPXS) method, ...
  • COMAP Early Science. V. Constraints and Forecasts at z ∼3 
    Chung, Dongwoo T.; Breysse, Patrick C.; Cleary, Kieran A.; Ihle, Håvard Tveit; Padmanabhan, Hamsa; Silva, Marta Bruno; Bond, J.

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present the current state of models for the z ∼ 3 carbon monoxide (CO) line intensity signal targeted by the CO Mapping Array Project (COMAP) Pathfinder in the context of its early science results. Our fiducial model, ...
