Description/Abstract | The X-ray cluster of galaxies IE 0839.9 + 2938 was serendipitously discovered with the Einstein Observatory.^CCD imaging at R and V wavelengths show that the color of the dominant elliptical galaxy of this cluster is significantly bluer than the colors of the next brightest cluster galaxies.^Strong emission lines, typical of cD galaxies with cooling flows, are present in the spectrum of the dominant galaxy, from which a redshift of 0.193 is derived.^The emitting line region is spatially resolved with an extension of about 13 kpc.^All the collected data suggest that this cluster is one of the most distant cooling flow clusters known to date.^28 refs. |
