The Evolution of Early-type Red Galaxies with the GEMS Survey: Luminosity-size and Stellar Mass-size Relations Since z=1
Daniel H. McIntosh, Eric F. Bell, Hans-Walter Rix +14
We combine HST/ACS imaging from the GEMS survey with redshifts and rest-frame quantities from COMBO-17 to study the evolution of morphologically early-type galaxies with red colors…
Cosmological weak lensing with the HST GEMS survey
Catherine Heymans, Michael L. Brown, Marco Barden +16
We present our cosmic shear analysis of GEMS, one of the largest wide-field surveys ever undertaken by the Hubble Space Telescope. Imaged with the Advanced Camera for Surveys (ACS)…
Evolution and Impact of Bars over the Last Eight Billion Years: Early Results from GEMS
S. Jogee, F. D. Barazza, H. -W. Rix +24
Bars drive the dynamical evolution of disk galaxies by redistributing mass and angular momentum, and they are ubiquitous in present-day spirals. Early studies of the Hubble Deep Fi…
The Fueling and Evolution of AGN: Internal and External Triggers
Shardha Jogee
In this chapter, I review the fueling and evolution of active galactic nuclei (AGN) under the influence of internal and external triggers, namely intrinsic properties of host galax…
Bar Evolution Over the Last Eight Billion Years: A Constant Fraction of Strong Bars in GEMS
S. Jogee, F. D. Barazza, H. -W. Rix +25
One third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve over cosmological tim…
GEMS: which galaxies dominate the z~0.7 ultraviolet luminosity density?
C. Wolf, E. F. Bell, D. H. McIntosh +14
We combine high-resolution images from GEMS with redshifts and spectral energy distributions from COMBO-17 to explore the morphological types of galaxies that dominate the z~0.7 UV…
