Observations of distant galaxies are important both for understanding how galaxies form and for probing the physical conditions of the Universe at early times. It is, however, very difficult to identify galaxies at redshifts z > 5, because they are so faint and have few spectral characteristics. We previously reported the probable identification of a galaxy(More)
We present deep 63-orbit HST/PC images at ∼0 .06 FWHM resolution in the filters B450 , V606 & I814 — as well as in redshifted Lyα — of the radio source LBDS 53W002, a compact narrow-line galaxy at z=2.390. These images allow us to distinguish several morphological components: (1) an unresolved nuclear point source (< ∼ 500 pc at z=2.390 for H0 =75, q0 =0),(More)
