Romteleskopet Planck har samlet data om den kosmiske bakgrunnsstrålingen. Kosmologene ved ITA har brukt dataene til å utvikle metoder som kan gi svar på spørsmålet om hvordan universet oppsto, om mørk materie og om mørk energi.
This BeyondPlanck paper presents new images of polarized emission from astrophysical sky components using never before combined data sets with a brand new approach.
Instrumental calibration is vital for the results of a CMB experiment to make sense. But how can we calibrate the instrument using measurements that we ideally need to calibrate the instrument to measure properly?
The BeyondPlanck collaboration has performed the most detailed analysis of the Planck Low Frequency Instrument (LFI) data to date, leading to a cleaner view of both the early universe and our own Milky Way.
Map-making of the Cosmic Microwave Background is an essential step that produces colourful 2D maps of the footprint of the early universe. Here cosmologists set the basis for the innovative map-making algorithm employed in BeyondPlanck.
The BeyondPlanck collaboration chases faint signals in the cosmic microwave background (CMB), an echo from the Big Bang, with this novel approach.
