HRI Observations of Powerful Radio Galaxies Positional Confirmation of Optically Quiet Quasars

摘要

This grant funded two HRI projects related to studies of active galactic nuclei under the ROSAT Guest Observer Program. One study produced complimentary data confirming that nature of candidate 'Optically Quiet Quasars' as part of a paper published in the Astrophysical JournaL The second study produced some ambigious results on the cluster environment of radio galaxies which and have been folded into an other ongoing study to produce a larger sample. Grant funds for both of these efforts have been expended.
