... We present preliminary results from two programs to image the host galaxies of radio-quiet quasars in 1.6 micron light using NICMOS camera 2 on HST. The high redshift program consists of QSOs covering the redshift range 0.8 < z < 4.4 and a range of QSO luminosities. Of the six objects for which data have been obtained the results range from no host galaxy detected, to an obvious galaxy with an interacting companion, to a possible high redshift galaxy cluster. ...

... This paper ( Burke et al. 2003 ) describes the creation of one such catalogue - the Southern Serendipitous High-redshift Archival ROSAT Cluster (SHARC) survey - which covers an area of 17.7 deg 2 and consists of 32 clusters with redshifts between 0.05 and 0.7 and X-ray luminosities between 7 x 10 42 and 4 x 10 44 erg/s: the high-redshift subsample contains 16 clusters with = 0.3 and X-ray luminosities greater than 2 x 10 43 erg/s (luminosities are quoted for the 0.5 - 2.0 keV energy band). ... 1997 ...
