Little is known about either the dark matter profile at large radii or the morphological properties of infalling galaxies at those redshifts where strong evolution is observed in the cluster cores. The proposal completed normally, with no reported problems. The proposal completed nominally. High redshift radio galaxies are fundamentally important probes of galaxy and cluster formation. The observations were completed as scheduled, and no anomalies were reported.
All exposures are internals.
The observations completed with no reported problems. The STIS provides us with a unique opportunity to study the early evolution of proto-planetary disks and their chances of survival in the harsh irradiated environments of OB class associations where most stars form. A wavelength calibration observation was also taken. The observations were completed as planned, and no anomalies were reported. The Fine Guidance Sensors were used to conduct high angular resolution observations of some of the SMC's hottest and most luminous objects by conducting a comprehensive survey of nearly every spectral type in the upper portion of the HR diagram.
