Scientific paper

For galaxy formation epochs now considered to be most likely, primeval galaxies will be infrared objects. The authors have therefore undertaken a deep survey of two "blank" fields at J and K (1.2 and 2.2 μm) to search for primeval galaxies. The one object discovered has infrared colours indicating that it is a faint foreground galaxy. The flux density of the brightest primeval galaxy which could have escaped detection, to 90 per cent confidence, in the survey of ≡1300 arcsec2 is ≡33 μJy at K. This limit constrains models of primeval galaxies by up to an order of magnitude over previous optical searches, for galaxy formation redshifts 5 < z < 10.
