Some systematic effects in the Planck temperature angular power spectrum compared to differences between several scenario of inflation. |
Planck aims at providing the definitive temperature angular power spectrum of the relic radiation as errors should be dominated by the cosmic variance up to the fifth peak. It implies a strict control of all possible systematic error sources. Among systematic effects are time dependent ones: cosmic ray hits have a huge short time impact while thermal variability of the HFI instrument and the Planck telescope have a soft but long time influence. I will compare the amplitude of such systematic effects to the precision that must be achieved to separate, for example, different scenario of the inflation. |
