Description
We report Chandra observations of the environment of the unusual
redshift 1 quasar PG1407+265 and discuss a new X-ray cluster found 1
arcminute from it. We discuss the X-ray variability of the quasar and
estimate the cluster contribution to the X-ray flux in previous lower
resolution observations. Optical observations complement the Chandra
data and allow us to estimate the physical properties of the cluster.
