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…
BVRI Light Curves for 22 Type Ia Supernovae
Adam G. Riess, Robert P. Kirshner, Brian P. Schmidt +6
We present 1210 Johnson/Cousins B,V,R, and I photometric observations of 22 recent type Ia supernovae (SNe Ia): SN 1993ac, SN 1993ae, SN 1994M, SN 1994S, SN 1994T, SN 1994Q, SN 199…
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…
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)…
The Performance and Scientific Rationale for an IR Imaging Fourier Transform Spectrograph on a Large Space Telescope
James R. Graham, Mark Abrams, C. Bennett +5
We describe a concept for an imaging spectrograph for a large orbiting observatory such as NASA's proposed Next Generation Space Telescope (NGST) based on an imaging Fourier transf…
