Scientific paper

We request 20ks of Chandra observations of the galaxy cluster around the z=0.84 quasar NVSS J003942-352803. The cluster was discovered in the course of an imaging program at the ESO NTT carried out to study the connection between Ly-alpha absorbers and galaxies in the field of intermediate-redshift (z~1) pairs of quasars. HST-STIS spectra of the two quasars in the field reveal several Ly-alpha absorbers around the quasar redshift of z=0.84. Chandra's superb spatial resolution will be able to separate the X-ray emission of the quasar from the X-ray emission of the galaxy cluster. By combining our STIS spectra with the proposed Chandra observations we will be able to probe both the warm gas in the UV, and the hot gas in the X-rays.
