Preprint typeset using LATEX style emulateapj v. 10/09/06 GOODS 850-5 — A Z> 4 GALAXY DISCOVERED IN THE SUBMILLIMETER?

We report an SMA interferometric identification of a bright submillimeter source, GOODS 850-5. This source is one of the brightest 850 μm sources in the GOODS-N but is extremely faint at all other wavelengths. It is not detected in the GOODS HST ACS images and only shows a weak 2 σ signal at 1.4 GHz. It is detected in the Spitzer IRAC bands and the MIPS 24 μm band, however, with very low fluxes...

ACCEPTED TO APJL Preprint typeset using LATEX style emulateapj v. 10/09/06 A LYMAN BREAK GALAXY CANDIDATE AT z ∼ 9 1

We report the discovery of a z ∼ 9 Lyman Break Galaxy (LBG) candidate, selected from the NICMOS Parallel Imaging Survey as a J-dropout with J110 H160 = 1.7. Spitzer/IRAC photometry reveals that the galaxy has a blue H160 3.6 μm color, and a spectral break between 3.6 and 4.5 μm. We interpret this break as the Balmer break, and derive a best-fit photometric redshift of z ∼ 9. We use Monte Carlo ...

SUBMITTED TO APJ Preprint typeset using LATEX style emulateapj v. 6/22/04

We propose that angular momentum transfer from the baryons to the Dark Matter (DM) during the early stages of galaxy formation can flatten the halo inner density profile and modify the halo dynamics. We compute the phase-space distribution function of DM halos, that corresponds to the density and anisotropy profiles obtained from N-body simulations in the concordance cosmology. We then describe...
