Abstract:
We present evidence for a significant overdensity of red galaxies, as
much as a factor of 14 over comparable field samples, in the field of
the z=1.47 radio galaxy B3 0003+387. The colors and luminosities of
the brightest red galaxies are consistent with their being at z>0.8.
The radio galaxy and one of the red galaxies are separated by 5" and
show some evidence of a possible interaction. However, the red
galaxies do not show any strong clustering around the radio galaxy or
around any of the brighter red galaxies. The data suggest that we are
looking at a wall or sheet of galaxies, possibly associated with the
radio galaxy at z=1.47. Spectroscopic redshifts of these red galaxies
will be necessary to confirm this large-scale structure.
