TL;DR: The Einstein X-ray Observatory (HEAO 2) as mentioned in this paper is a fully imaging focusing Xray telescope with an angular resolution of a few arc sec, a field of view of up to one deg, and a sensitivity several hundred times greater than previously available in any Xray astronomy experiment.
Journal ArticleDOI
Discovery of an X-ray star association in VI Cygni (CYG OB2)
F. R. Harnden,G. Branduardi,Martin Elvis,Paul Gorenstein,J. E. Grindlay,J. P. Pye,Robert Rosner,K. Topka,G. S. Vaiana +8 more
TL;DR: A group of six X-ray sources located within 0.4 deg of Cygnus X-3 has been discovered with the Einstein Observatory as mentioned in this paper, and five of them correspond to stars in the heavily obscured OB association VI Cygni.
Journal ArticleDOI
A high-sensitivity X-ray survey using the Einstein Observatory and the discrete source contribution to the extragalactic X-ray background
Riccardo Giacconi,J. Bechtold,G. Branduardi,William R. Forman,J. P. Henry,C. Jones,E. M. Kellogg,H. van der Laan,W. Liller,Herman L. Marshall,S. S. Murray,John P. Pye,Ethan J. Schreier,Wallace L. W. Sargent,F. D. Seward,Harvey Tananbaum +15 more
TL;DR: In this paper, the number-intensity relationship for extragalactic sources is evaluated, and the consequences of the findings are discussed with particular emphasis on the discrete source contribution to the X-ray background, concluding that a large fraction of the background is due to previously unresolved discrete sources.
Journal ArticleDOI
Detection of X-ray emission from distant clusters of galaxies
J. P. Henry,G. Branduardi,Daniel G. Fabricant,E. D. Feigelson,S. S. Murray,Harvey Tananbaum,U. Briel,A. M. Soltan +7 more
TL;DR: In this paper, the first extensive detection of X-ray emission from clusters of galaxies at cosmological distances was reported, and the properties of these objects are similar to those observed in objects at low redshifts.
