Structure in the COBE differential microwave radiometer first year maps

TL;DR: In this paper, the first year of data from the differential microwave radiometers on the Cosmic Background Explorer was presented, and the angular autocorrelation of the signal in each radiometer channel and cross-correlation between channels were consistent and gave a primordial fluctuation power-law spectrum with index of 1.1 +/- 0.5, and an rms-quadrupole-normalized amplitude of 16 +/- 4 micro-K.
Journal ArticleDOI

A Preliminary measurement of the Cosmic Microwave Background spectrum by the Cosmic Background Explorer (COBE) satellite

TL;DR: In this paper, a preliminary spectrum is presented of the background radiation between 1 and 20 cm from regions near the north Galactic pole, as observed by the FIRAS instrument on the COBE satellite.
Journal ArticleDOI

The COBE Mission: Its Design and Performance Two Years after Launch

TL;DR: The COBE mission as mentioned in this paper is the first space mission devoted to cosmology and is described and the spacecraft concepts central to enabling the mission to achieve its scientific objectives are examined, including the major components of the COBE instrument and spacecraft modules.
Journal ArticleDOI

Dipole Anisotropy in the COBE Differential Microwave Radiometers First-Year Sky Maps

TL;DR: In this article, the authors presented a determination of the cosmic microwave background dipole amplitude and direction from the COBE Differential Microwave Radiometers (DMR) first year of data.
