New High-Redshift Radio Galaxies from the MIT-Green Bank Catalog
Daniel Stern, Arjun Dey, Hyron Spinrad +4
We present optical identifications and redshifts for seventeen new high-redshift radio sources. Fifteen of these sources are radio galaxies; the remaining two are high-redshift, st…
Induced star formation and morphological evolution in very high redshift radio galaxies
Wil van Breugel, A. Stanford, A. Dey +5
Near-infrared, sub-arcsecond seeing images obtained with the W. M. Keck I Telescope of show strong evolution at rest--frame optical} wavelengths in the morphologies of high redshif…
A z=5.34 Galaxy Pair in the Hubble Deep Field
Hyron Spinrad, Daniel Stern, Andrew Bunker +5
We present spectrograms of the faint V-drop (V(606) = 28.1, I(814) = 25.6) galaxy pair HDF3-951.1 and HDF3-951.2 obtained at the Keck II Telescope. Fernandez-Soto, Lanzetta, & Yahi…
HST images and properties of the most distant radio galaxies
L. Pentericci, H. J. A. Rottgering, G. K. Miley +4
We present Hubble Space Telescope images of 11 high redshift radio galaxies (between and ). The galaxies were observed with the WFPC2 camera in a broad band filter (…
Keck Spectroscopy and NICMOS Photometry of a Redshift z=5.60 Galaxy
R. J. Weymann, D. Stern, A. Bunker +4
We present Keck LRIS spectroscopy along with NICMOS F110W (~J) and F160W (~H) images of the galaxy HDF4-473.0 (hereafter 4-473) in the Hubble Deep Field, with a detection of an emi…
A Galaxy at z=5.34
Arjun Dey, Hyron Spinrad, Daniel Stern +2
We report the discovery of Lyman alpha emission from a galaxy at z=5.34, the first object at z>5 with a spectroscopically confirmed redshift. The faint continuum emission (m(8000A)…
