Title: A Deep NIR Survey of the HDF-South Flanking Fields

Abstract: Studies of the rest-frame optical properties of galaxies beyond z~ 2 have been hampered by the lack of deep near-infrared (NIR) observations over sufficiently large fields. The IR sideport imager on the Blanco 4m offers the opportunity for a deep extra-galactic survey of unprecedented area. As part of an ambitious multi-wavelength survey conducted in collaboration with Chilean astronomers we propose to obtain very deep J, H, K_s images of the 10' \times 10' ``Flanking Fields'' area of the Hubble Deep Field South (HDF-S). These data complement extremely deep VLT+ISAAC images of the HDF-S proper (the deepest NIR data yet obtained of any field), and a broad array of supporting data at other wavelengths. The 10' \times 10' area is well matched to that of scheduled SIRTF observations of HDF-S, and planned Chandra data. The main science goals are to determine the spectral energy distributions, surface density and clustering of galaxies with evolved stellar populations at z>2, and to constrain the dust content and ages of ~ 100 Lyman-break galaxies from their rest-frame optical properties. In the spirit of the HDF campaigns we intend to make the reduced images publicly available.
