Surface Density of Extremely Red Objects with R-J≥5

An error occurred while generating the citation.

Abstract

A catalogue of galaxies with extremely red colours (R-J≥5), covering 8.43 square degrees has been selected from optical and near-infrared data. Based on their bright near-infrared magnitude and their very red colour, these objects are likely to be very massive galaxies with little or no ongoing star formation. We have derived a surface density of 0.0396 ± 0.0011 arcmin⁻² (Poisson uncertainties) for these Extremely Red Objects.
