(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The CO Mapping Array Project (COMAP) aims to use line-intensity mapping of carbon monoxide (CO) to trace the distribution and global properties of galaxies over cosmic time, back to the Epoch of Reionization (EoR). To ...

S.; Padmanabhan, Hamsa; Pearson, Timothy J.; Rennie, Thomas J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We describe the first-season CO Mapping Array Project (COMAP) analysis pipeline that converts raw detector readouts to calibrated sky maps. This pipeline implements four main steps: gain calibration, filtering, data ...
  • COMAP Early Science. IV. Power Spectrum Methodology and Results

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, ...
