Cosmoglobe

Mapping the universe from the Milky Way to the Big Bang

Cosmoglobe will integrate the world’s best data from radio to sub-mm wavelengths into a single global model. Cosmoglobe will extend the current global model by

  • one order of magnitude in polarization sensitivity
  • three orders of magnitude in frequency
  • a factor of five in angular resolution
  • introducing three new cosmological components (high-redshift CO, CIB and SZ)
  • adding one new astrophysical component (zodical light emission)
  • integrating at least 11 new observational data sets
  • supporting three-dimensional data sets

Scientific objectives

  • Combine with SPIDER to constrain primordial gravitational waves
  • Combine with PASIPHAE to get 3D maps of the magnetic field in the Milky Way
  • Combine with COMAP to get 3D maps of CO intensity at high redshifts
  • Cosmoglobe will be used for foreground modelling and forecasting for future experiments like LiteBIRD

Financing

Cosmoglobe is funded by an ERC CoG grant. The Cosmoglobe project will start in 2019 and last for five years.
