Cosmic Microwave Background Radiation, DMR


The COBE DMR has found anisotropies in the cosmic microwave background on all scales from the nominal beam size of 7-degrees up to the full sky at a typical level of one part in 100,000 to a few parts per million. These anisotropies are interpreted as imprints of the seeds that eventually grew under the influence of gravity to galaxies, clusters of galaxies, and clusters of clusters of galaxies. They also indicate that we should eventually expect to find even larger scale structures. They also give us a clue to how the Universe originated - how space and time and all the other contents of the Universe came into being. Two of the four years of the COBE DMR data have been released. Data processing of all four years are in progress and the full four year data were released in January 1996. The DMR team had a large number of members over the years in addition to those from the COBE science working group that participated.
