Chandra Multiwavelength Project: Normal Galaxies at Intermediate Redshift
D. -W. Kim, W. A. Barkhouse, E. R. Colmenero +11
(abridged) We have investigated 136 Chandra extragalactic sources without broad optical emission lines, including 93 galaxies with narrow emission lines (NELG) and 43 with only abs…
The First Chandra Field
Martin C. Weisskopf, Thomas L. Aldcroft, Robert A. Cameron +6
Before the official first-light images, the Chandra X-Ray Observatory obtained an X-ray image of the field to which its focal plane was first exposed. We describe this historic obs…
X-ray Cluster Associated with the z=1.063 CSS Quasar 3C 186: The Jet is NOT Frustrated
Aneta Siemiginowska, C. C. Cheung, Stephanie LaMassa +6
We report the Chandra discovery of an X-ray cluster at redshift z = 1.063 associated with the Compact Steep Spectrum radio loud quasar 3C 186 (Q0740+380). Diffuse X-ray emission is…
Discovery of a Galaxy Cluster in the Foreground of the Wide-Separation Quasar Pair UM425
Paul J. Green, Leopoldo Infante, Sebastian Lopez +2
We report the discovery of a cluster of galaxies in the field of UM425, a pair of quasars separated by 6.5arcsec. Based on this finding, we revisit the long-standing question of wh…
