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
Measurement of the Cosmic Microwave Background spectrum by the COBE FIRAS instrument
John C. Mather,Edward Cheng,D. A. Cottingham,Robert E. Eplee,Dale J. Fixsen,Tilak Hewagama,R. B. Isaacman,K. A. Jensen,S. S. Meyer,Peter D. Noerdlinger,S. M. Read,L. P. Rosen,Richard A. Shafer,Edward L. Wright,Charles L. Bennett,N. W. Boggess,Michael G. Hauser,T. Kelsall,Samuel H. Moseley,Robert F. Silverberg,George F. Smoot,Rainer Weiss,David T. Wilkinson +22 more
TL;DR: In this paper, the Far-Infrared Absolute Spectrophotomer (FIRAS) instrument on the Cosmic Background Explorer (COBE) satellite was used to obtain a blackbody spectrum within 3.4 x 10(exp -8) ergs/sq cm/s/sr cm over the frequency range from 2 to 20/cm (5-0.5 mm).
Journal ArticleDOI
Morphology, near infrared luminosity, and mass of the galactic bulge from Cobe dirbe observations
E. Dwek,R. G. Arendt,M. G. Hauser,T. Kelsall,Carey M. Lisse,S. H. Moseley,Robert F. Silverberg,T. J. Sodroski,Janet Weiland +8 more
TL;DR: In this paper, the authors used triaxial analytical functions to represent the volume emissivity of the source and confirmed the bar-like nature of the bulge and showed that triaxially Gaussian-type functions provide a better fit to the data than other classes of functions, including an axisymmetric spheroid.
Journal ArticleDOI
A Preliminary measurement of the Cosmic Microwave Background spectrum by the Cosmic Background Explorer (COBE) satellite
John C. Mather,E. S. Cheng,Rick Shafer,Charles L. Bennett,N. W. Boggess,E. Dwek,M. G. Hauser,T. Kelsall,S. H. Moseley,Robert F. Silverberg +9 more
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
Preliminary spectral observations of the Galaxy with a 7 deg beam by the Cosmic Background Explorer (COBE)
Edward L. Wright,J. C. Mather,Charles L. Bennett,E. S. Cheng,R. A. Shafer,D. J. Fixsen,R. E. Eplee,R. B. Isaacman,S. M. Read,N. W. Boggess,Samuel Gulkis,M. G. Hauser,Michael A. Janssen,T. Kelsall,Philip Lubin,S. S. Meyer,S. H. Moseley,T. L. Murdock,Robert F. Silverberg,G. F. Smoot,Rainer Weiss,David T. Wilkinson +21 more
TL;DR: The FIR absolute spectrophotometer (FIRAS) on the Cosmic Background Explorer (COBE) has carried out the first all-sky spectral line survey in the FIR region, as well as mapping spectra of the Galactic dust distribution at below 100 microns as discussed by the authors.
