Testing the CMB Data for Systematic Effects

  title={Testing the CMB Data for Systematic Effects},
  author={Louise M. Griffiths and C. Lineweaver},
  journal={arXiv: Astrophysics},
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



Calibration and systematic error analysis for the COBE-DMR four-year sky maps

The Differential Microwave Radiometers (DMR) instrument aboard the Cosmic Background Explorer (COBE) has mapped the full microwave sky to mean sensitivity 26 mu K per 7 degrees held of view. The

Foregrounds Removal and CMB Fluctuations in a Multiband Anisotropy Experiment: ARGO 1993

We present the results of a diffuse radiation survey carried out at millimeter and submillimeter wavelengths in the Aries and Taurus sky regions. A balloon-borne telescope with 0.°86 FWHM resolution

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.

High-Resolution Observations of the Cosmic Microwave Background Power Spectrum with ACBAR

We report the first measurements of anisotropy in the cosmic microwave background (CMB) radiation with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). The instrument was installed on the

First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Determination of Cosmological Parameters

WMAP precision data enable accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a nearly scale-invariant adiabatic

Mapping the Cosmic Microwave Background Anisotropy:The First Flight of the QMAP Experiment

We report on the first flight of the balloon-borne QMAP experiment. The experiment is designed to make a map of the cosmic microwave background (CMB) anisotropy on angular scales from 0.°70 to

First Intrinsic Anisotropy Observations with the Cosmic Background Imager

We present the first results of observations of the intrinsic anisotropy of the cosmic microwave background radiation with the Cosmic Background Imager from a site at 5080 m altitude in northern

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.

A search for anisotrophy in the cosmic microwave background on intermediate angular scales

The results of a search for anisotropy in the cosmic microwave background on angular scales near 1 deg are presented. Observations were simultaneously performed in bands centered at frequencies of 6,

Cosmic confusion: degeneracies among cosmological parameters derived from measurements of microwave background anisotropies

ABSTRA C T In the near future, observations of the cosmic microwave background (CMB) anisotropies will provide accurate determinations of many fundamental cosmological parameters. In this paper, we
