The Nature of the Compact/Symmetric Near-IR Continuum Source in 4C 40.36
E. Egami, L. Armus, G. Neugebauer +3
Using NICMOS on HST, we have imaged the emission-line nebulae and the line-free continuum in 4C 40.36, a ultra-steep spectrum FR II radio galaxy at z=2.269. The line-free continuum…
NICMOS Observations of Luminous and Ultraluminous Infrared Galaxies
A. S. Evans
HST NICMOS observations of a sample of 24 luminous (LIGs: L_(IR) [8-1000 microns] = 10^(11.0-11.99) L_sun) and ultraluminous (ULIGs: L_(IR) > 10^(12.0) L_sun) infrared galaxies are…
HST NICMOS Observations of FSC10214+4724
A. S. Evans, N. Z. Scoville, N. Dinshaw +4
High-resolution, 1.10, 2.05, 2.12, and 2.15 micron imaging of the gravitationally lensed system FSC10214+4724 are presented. These data extend HST observations of the lens system t…
CO Emission in Radio Galaxies at Low and High Redshift
A. S. Evans
CO observations of 0<z<4 radio galaxies are presented. The L_CO upper limits for the high-redshift powerful radio galaxies (HzPRGs: z > 1, P_408MHz > 10^27 Watts/Hz) are consistent…
The Epoch of Major Star Formation in High-z Quasar Hosts
Yoshiaki Taniguchi, Nobuo Arimoto, Takashi Murayama +3
We present the results of our observing program on near infrared spectroscopy of high-redshift quasars which have been undertaken both at Kitt Peak National Observatory and at Maun…
