A High-Redshift Z(=0.95) Cluster Revealed by a First Bent-Double Radio Source

To complete the analysis and publication of this observation of a high redshift cluster associated with a FIRST bent-double radio source. Although we had proposed a 95 ksec observation, we were give 20 ksec to just try and detect the cluster. In fact, the cluster was detected at the > 5 sigma level, and we plan to repropose a longer observation in Cycle 6. he present Chandra observation shows that the X-ray emission follows the distribution of the optical galaxies. The spectrum, which is very crude given the small number of counts, is nonetheless consistent with the temperature expected from the cluster sigma-T relation. The luminosity is about 2e44, which is consistent with the L _X-sigma relation. We will submit a short paper on the detection soon.
