4-Year COBE DMR Cosmic Microwave Background Observations: Maps and Basic Results
C. L. Bennett, A. Banday, K. M. Gorski +7
The cosmic microwave background radiation provides unique constraints on cosmological models. In this Letter we present a summary of the spatial properties of the cosmic microwave…
Calibration and Systematic Error Analysis For the COBE-DMR Four-Year Sky Maps
A. Kogut, A. J. Banday, C. L. Bennett +8
The Differential Microwave Radiometers (DMR) instrument aboard the Cosmic Background Explorer (COBE) has mapped the full microwave sky to mean sensitivity 26 uK per 7 deg field of…
The Dipole Observed in the COBE DMR Four-Year Data
C. H. Lineweaver, L. Tenorio, G. F. Smoot +3
The largest anisotropy in the cosmic microwave background (CMB) is the mK dipole assumed to be due to our velocity with respect to the CMB. Using the four year data set…
Correlated Errors in the COBE DMR Sky Maps
C. H. Lineweaver, G. F. Smoot, C. L. Bennett +6
The {\it COBE} DMR sky maps contain low-level correlated noise. We obtain estimates of the amplitude and pattern of the correlated noise from three techniques: angular averages of…
Cosmic Temperature Fluctuations from Two Years of COBE DMR Observations
C. Bennett, A. Kogut, G. Hinshaw +15
The first two years of COBE DMR observations of the CMB anisotropy are analyzed and compared with our previously published first year results. The results are consistent, but the a…
