Under the assumption that the concordancecold dark matter (CDM) model is the correct model, we test the cosmic microwave background (CMB) anisotropy data for systematic effects by examining the band pass temperature residuals with respect to this model. Residuals are plotted as a function of `, galactic latitude, frequency, calibration source, instrument type and several other variables that may be associated with potential systematic effects. Linear fitting to the resid- uals indicates no… 

Exploring cosmic origins with CORE: Mitigation of systematic effects

We present an analysis of the main systematic effects that could impact the measurement of CMB polarization with the proposed CORE space mission. We employ timeline-to-map simulations to verify that

Radical Compression of Cosmic Microwave Background Data

A method for approximating the likelihood that takes power spectrum constraints, e.g., "band-powers," as inputs, is presented, and a bias which results if one approximates the probability distribution of the band-power errors as Gaussian is identified.

The peak shape is consistent with inflation-inspired flat, cold dark matter plus cosmological constant models of structure formation with adiabatic, nearly scale invariant initial conditions and presents a great challenge to defect models.
