The Gemini Deep Deep Survey: I. Introduction to the Survey, Catalogs and Composite Spectra
Roberto G. Abraham, Karl Glazebrook, Patrick J. McCarthy +9
The Gemini Deep Deep Survey (GDDS) is an ultra-deep (K<20.6 mag, I<24.5 mag) redshift survey targeting galaxies in the "redshift desert" between 1<z<2. The primary goal of the surv…
Red Nuggets at High Redshift: Structural Evolution of Quiescent Galaxies Over 10 Gyr of Cosmic History
Ivana Damjanov, Roberto G. Abraham, Karl Glazebrook +15
We present an analysis of the size growth seen in early-type galaxies over 10 Gyr of cosmic time. Our analysis is based on a homogeneous synthesis of published data from 17 spectro…
Evolved Galaxies at z > 1.5 from the Gemini Deep Deep Survey: The Formation Epoch of Massive Stellar Systems
Patrick J. McCarthy, Damien Le Borgne, David Crampton +11
We present spectroscopic evidence from the Gemini Deep Deep Survey (GDDS) for a significant population of color-selected red galaxies at 1.3 < z < 2.2 whose integrated light is dom…
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…
Three Lyman-alpha Emitters at z approx 6: Early GMOS/Gemini Data from the GLARE Project
Elizabeth R. Stanway, Karl Glazebrook, Andrew J. Bunker +14
We report spectroscopic detection of three z~6 Lyman-alpha emitting galaxies, in the vicinity of the Hubble Ultra Deep Field, from the early data of the Gemini Lyman- at Reioni…
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…
Gemini Deep Deep Survey VI: Massive Hdelta-strong galaxies at z=1
Damien Le Borgne, Roberto Abraham, Kathryne Daniel +11
We show that there has been a dramatic decline in the abundance of massive galaxies with strong Hdelta stellar absorption lines from z=1.2 to the present. These ``Hdelta-strong'',…
When do early-type galaxies form?
Roberto G. Abraham, Patrick J. McCarthy, Erin Mentuch +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys to measure the mass density function of morphologically selected early-type galaxies in the Gemini Deep Deep S…
Deep Spectroscopy of the Host Galaxy of a Tidal Disruption Flare in A1795
W. Peter Maksym, Melville Ulmer, Kathy Roth +5
A likely tidal disruption of a star by the intermediate-mass black hole (IMBH) of a dwarf galaxy was recently identified in association with Abell 1795. Without deep spectroscopy f…
The Gemini Deep Deep Survey: III. The abundance of massive galaxies 3-6 billion years after the Big Bang
Karl Glazebrook, Roberto Abraham, Patrick McCarthy +9
Hierarchical galaxy formation is the model whereby massive galaxies form from an assembly of smaller units. The most massive objects therefore form last. The model succeeds in desc…
