Scientific paper

After extensive testing of the quality of the data and the codes, some results from the comparison of the HEAO-A2 and COBE data are now available. The major emphasis of our first detailed analysis is on the Shapley Supercluster (SSC), a region which contains a large overdensity of clusters and for which diffuse gas might be found on scales exceeding 10 Mpc. Not only is there some excess X-ray emission associated with the SSC, but there appears also to be a microwave background structure in this region. The analysis of the structure, which may be associated with the Sunyaev-Zel'dovich or Rees-Sciama effects (the major aims of this work), is complicated by underlying primordial fluctuations in the background radiation and proximity to the Galactic plane. If it is real, the microwave background radiation structure has interesting implications for the temperature, density, and extent of supercluster gas (on the Sunyaev-Zel'dovich effect interpretation), and on the mass of the region (on the Rees-Sciama effect interpretation).
