Grindlay, J. E. ; Parsignault, D. R. ; Gursky, H. ; Brinkman, A. C. ; Heise, J. ; Harris, D. E. Abstract A significantly improved position for the X-ray source 3U 1921 + 43 has been obtained by ANS and Uhuru. The combined ANS-Uhuru error box is only about 7 by 7 arcmin and is centered on the cD galaxy in the Abell 2319 cluster of galaxies. Radio observations of this cluster indicate that the emission at 610 MHz includes several discrete sources and a weak extended component. This strengthens the general association between extended radio halos and X-ray emission from clusters of galaxies. The radio halo fills the X-ray error box and is consistent with the limits reported for the angular size of the X-ray source Publication: The Astrophysical Journal Pub Date: June 1977 DOI: 10.1086/182442 Bibcode: 1977ApJ...214L..57G Keywords: Galactic Clusters; Position Errors; Radio Astronomy; X Ray Astronomy; Astronomical Netherlands Satellite; Error Analysis; Spaceborne Astronomy; Uhuru Satellite; Astronomy full text sources ADS | data products NED (2) SIMBAD (1)
