The first detection of [OIII] emission from high-redshift damped Lyman-alpha galaxies
S. J. Weatherley, S. J. Warren, P. Moller +3
We present the detection of [OIII] emission lines from the galaxies responsible for two high-redshift z>1.75 damped Lyman-alpha (DLA) absorption lines. These are the first detectio…
Evolution of Disk Galaxies in the GOODS-South Field: Number Densities and Size Distribution
S. Ravindranath, H. C. Ferguson, C. Conselice +14
We examine the evolution of the sizes and number densities of disk galaxies using the high resolution images obtained by the Great Observatories Origins Deep Survey (GOODS) with th…
Direct evidence for an early reionization of the Universe?
N. Panagia, S. M. Fall, B. Mobasher +5
We examine the possible reionization of the intergalactic medium (IGM) by the source UDF033238.7-274839.8 (hereafter HUDF-JD2), which was discovered in deep {\it HST}/VLT/{\it Spit…
Heavy Element Abundances and Dust Depletions in the Host Galaxies of Three Gamma-Ray Bursts
S. Savaglio, S. M. Fall, F. Fiore
We have derived the column densities of heavy elements in three gamma-ray burst (GRB) optical transients, associated with the circumburst or interstellar medium (ISM) of the host g…
Star Formation, Metallicity and Dust Properties Derived from the SAPM Galaxy Survey Spectra
S. Charlot, G. Kauffmann, M. Longhetti +4
We have derived star formation rates (SFRs), gas-phase oxygen abundances and effective dust absorption optical depths for a sample of galaxies drawn from the Stromlo-APM redshift s…
A Possible New Population of Sources with Extreme X-Ray / Optical Ratios
Anton M. Koekemoer, D. M. Alexander, F. E. Bauer +13
We describe a possible new class of X-ray sources that have robust detections in ultra-deep Chandra data, yet have no detections at all in our deep multi-band GOODS Hubble Space Te…
