Extremely Red Objects in the Field of QSO 1213-0017: A Galaxy Concentration at z=1.31
Michael C. Liu, Arjun Dey, James R. Graham +2
We have discovered an excess of extremely red objects (EROs) surrounding the z=2.69 quasar QSO 1213-0017 (UM 485). Optical/IR colors for these galaxies are consistent with z=1-2 el…
NICMOS Imaging of High-Redshift Radio Galaxies
A. Zirm, A. Dey, M. Dickinson +6
We have obtained near-infrared (1.6 micron) images of 11 powerful 3CR radio galaxies at redshifts 0.8 < z < 1.8 using NICMOS on board HST. The high angular resolution permits a det…
The Unusual Infrared Object HDF-N J123656.3+621322
Mark Dickinson, Christopher Hanley, Richard Elston +11
We describe an object in the Hubble Deep Field North with very unusual near-infrared properties. It is readily visible in Hubble Space Telescope NICMOS images at 1.6um and from the…
A search for the submillimetre counterparts to Lyman break galaxies
Scott C. Chapman, Douglas Scott, Charles C. Steidel +7
We have carried out targetted sub-mm observations as part of a programme to explore the connection between the rest-frame UV and far-IR properties of star-forming galaxies at high…
Young stars and non-stellar emission in the aligned radio galaxy 3C 256
Chris Simpson, Peter Eisenhardt, Lee Armus +8
We present ground-based images of the z=1.824 radio galaxy 3C 256 in the standard BVRIJHK filters and an interference filter centered at 8800A, a Hubble Space Telescope image in a…
