About the Object Object Description: Galaxies in the Hubble Ultra Deep Field (HUDF) Position (J2000): R.A. 03h 32m 40s.0 Dec. -27° 48' 00" Constellation: Fornax Dimensions: The full HUDF image is 3 arcminutes square. About the Data Data Description:
The science data were selected based on findings from The Grism-ACS Program for Extragalactic Science (GRAPES), HST proposal 9793: S. Malhotra et. al. The science team includes: N. Pirzkal (STSCI/ESA) S. Malhotra and J. Rhoads (Arizona State University), and C. Xu (Shanghai Institute of Technical Physics).
This image of the HUDF was created from HST data from the following proposal: 9978: S. Beckwith, S. Malhotra, M. Giavalisco, N. Panagia, J. Rhoads, M. Stiavelli, R. Somerville, S. Casertano, B. Margon, C. Blades, J. Caldwell, and M. Clampin (STScI), M. Corbin (STScI/CSC), M. Dickinson, H. Ferguson, and A. Fruchter (STScI), R. Hook (STScI/ECF), S. Jogee, A. Koekemoer, R. Lucas, M. Sosey, and L. Bergeron (STScI).
The NICMOS HUDF data were from proposal 9803: R. Thompson (University of Arizona), G. Illingworth and R. Bouwens (university of California, Santa Cruz), M. Dickinson (STScI), D. Eisenstein and X. Fan (University of Arizona), M. Franx (University of Leiden), M. Rieke (University of Arizona), A. Riess (STScI), and P. van Dokkum (Yale University).
The Spitzer science team includes: H. Yan (Caltech), M Dickinson (NOAO), D. Stern and P. Eisenhardt (Jet Propulsion Lab), R.-R. Chary (Caltech), M. Giavalisco (STScI), H. Ferguson and S. Casertano (STScI), C. Conselice (Caltech), C. Papovich (Steward Observatory), W. Reach (Caltech), N. Grogin (STScI), L. Moustakas (Jet Propulsion Lab), and M. Ouchi (STScI).
