Abstract:
The CO Mapping Array Project Galactic Plane Survey (COMAP GPS) is a radio continuum and radio recombination line survey between 26 and 34 GHz at a resolution of 4.5 arcminutes. The survey will span Galactic longitudes of 20 < l < 270 and latitudes of |b| < 2 with an expected completion date in 2025. Complimenting COMAP's main cosmological goals (mapping star formation history through observing the redshifted CO-line) the COMAP GPS aims to investigate star formation by observing Galactic Hii regions, producing the highest-resolution Galactic AME catalogue to date and creating diffuse emission templates for better subtraction of Galactic emission from CMB maps.
In this talk, I will present our first published results from the COMAP early science series, alongside a sneak peek at the next wave of results to be published in the coming months - many of which focus on the search for spinning dust emission (AME) at scales of a few arc-minutes. I will discuss our first AME searches in the region around Westerhout 43, alongside our latest results following up on the QUIJOTE and Planck AME catalogues (Poidevin et al., 2023, Planck Int. XV). I will show how COMAP data allows us to localise AME to specific sub-structures in these vast complexes - notably in W47 and W52. Finally, I will discuss our next results from an extension of the survey to Barnard 30 in the Lambda Orionis region.
