A Surprisingly High Pair Fraction for Extremely Massive Galaxies at z ~ 3 in the GOODS NICMOS Survey

Size evolution of the most massive galaxies at 1.7<z<3 from GOODS NICMOS survey imaging
Fernando Buitrago, Ignacio Trujillo, Christopher J. Conselice +3
We measure the sizes of 82 massive (M>10^11 M_sun) galaxies at 1.7<z<3 utilizing deep HST NICMOS data taken in the GOODS North and South fields. Our sample is almost an order of ma…
Red Nuggets at z~1.5: Compact passive galaxies and the formation of the Kormendy Relation
Ivana Damjanov, Patrick J. McCarthy, Roberto G. Abraham +13
We present the results of NICMOS imaging of a sample of 16 high mass passively evolving galaxies with 1.3<z<2, taken primarily from the Gemini Deep Deep Survey. Around 80% of galax…
Spectroscopic Confirmation of Faint Lyman Break Galaxies at Redshifts Four and Five in the Hubble Ultra Deep Field
James E. Rhoads, Sangeeta Malhotra, Norbert Pirzkal +6
We present the faintest spectroscopically confirmed sample of redshift four and five Lyman break galaxies to date. The sample is based on slitless grism spectra of the Hubble Ultra…
An Overdensity of i-dropouts Among A Population of Excess Field Objects in the Virgo Cluster
Haojing Yan, Nimish Hathi, Rogier Windhorst
Using a set of deep imaging data obtained by the ACS on the HST shortly after its deployment, Yan, Windhorst & Cohen (2003) found a large number of F775W-band dropouts (i-dropouts)…
Rest-Frame Ultraviolet to Near Infrared Observations of an Interacting Lyman Break Galaxy at z = 4.42
Joshua D. Younger, Jia-Sheng Huang, Giovanni G. Fazio +11
We present the rest-frame ultraviolet through near infrared spectral energy distribution for an interacting Lyman break galaxy at a redshift z=4.42, the highest redshift merging sy…
The Gemini Deep Deep Survey: VIII. When Did Early-type Galaxies Form?
Roberto G. Abraham, Preethi Nair, Patrick J. McCarthy +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys (Ford et al. 2003) to measure the cumulative mass density in morphologically-selected early-type galaxies over…
The Stellar Masses and Star Formation Histories of Galaxies at z ~ 6: Constraints from Spitzer Observations in the Great Observatories Origins Deep Survey
Haojing Yan, Mark Dickinson, Mauro Giavalisco +3
Using the deep Spitzer IRAC observations of the Great Observatories Origins Deep Survey (GOODS), we study the stellar masses and star formation histories of galaxies at z ~ 6. Our…
Rest-frame Ultraviolet-to-Optical Properties of Galaxies at z ~ 6 and 5 in the Hubble Ultra Deep Field: from Hubble to Spitzer
Haojing Yan, Mark Dickinson, Daniel Stern +11
We use data from the first epoch of observations with the IRAC/Spitzer for the GOODS to detect and study a collection of LBGs at z ~ 6 to 5 in the HUDF, six of which have spectrosc…
How JWST can measure First Light, Reionization and Galaxy Assembly
R. A. Windhorst, S. H. Cohen, R. A. Jansen +2
We summarize the design and performance of the James Webb Space Telescope that is to be launched to an L2 orbit in 2011, and how it is designed, in particular, to study the epochs…
An overdensity of galaxies at z=5.9 +/-0.2 in the Ultra Deep Field confirmed using the ACS grism
S. Malhotra, J. E. Rhoads, N. Pirzkal +17
We present grism spectra taken with the Advanced Camera for Surveys to identify 29 red sources with (i'-z') > 0.9 in the Hubble Ultra Deep Field (HUDF). Of these 23 are found to be…
High-Redshift Extremely Red Objects in the HST Ultra Deep Field Revealed by the GOODS IRAC Observations
Haojing Yan, Mark Dickinson, Peter R. M. Eisenhardt +9
Using early data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope, taken for the Great Observatories Origins Deep Survey (GOODS), we identify and study objects…
A Redshift z=5.4 Lyman alpha Emitting Galaxy with Linear Morphology in the GRAPES/UDF Field
James E. Rhoads, Nino Panagia, Rogier A. Windhorst +21
We have discovered an extended Lyman alpha plume associated with a compact source at redshift 5.4 in slitless spectroscopic data from the Grism ACS Program for Extragalactic Scienc…
Candidates of z ~ 5.5--7 Galaxies in the HST Ultra Deep Field
Haojing Yan, Rogier A. Windhorst
We report results from our --7 galaxy search in the HST Ultra Deep Field (UDF). Using the 400-orbit of ACS data, we found 108 plausible (or $z\sime…
The Major Sources of the Cosmic Reionizing Background at z ~ 6
Haojing Yan, Rogier A. Windhorst
In this paper, we address which sources contributed most of the reionizing photons. Our argument assumes that the reionization ended around z ~ 6 and that it was a relatively quick…
Hubble Space Telescope images of submillimeter sources: large, irregular galaxies at high redshift
S. C. Chapman, R. Windhorst, S. Odewahn +2
We present new Hubble Space Telescope STIS, high-resolution optical imaging of a sample of 13 submillimeter (submm) luminous galaxies, for which the optical emission has been pinpo…
Searching for z ~ 6 Objects with the HST Advanced Camera for Surveys: Preliminary Analysis of a Deep Parallel Field
Haojing Yan, Rogier A. Windhorst, Seth H. Cohen
Recent results suggest that z ~ 6 marks the end of the reionization era. A large sample of objects at z ~ 6, therefore, will be of enormous importance, as it will enable us to obse…
