New Frontiers in Cosmology and Galaxy Formation: Challenges for the Future
Richard Ellis, Joseph Silk
(Abridged) Cosmology faces three distinct challenges in the next decade. (1) The dark sector, both dark matter and dark energy, dominates the Universe. Key questions include determ…
Reflections of Cluster Assembly in the Stellar Populations and Dynamics of Member Galaxies
Sean M. Moran, Richard S. Ellis, Tommaso Treu +1
We combine optical (HST) and UV (GALEX) imaging of two intermediate redshift galaxy clusters with spectroscopy of member galaxies, to study the relation between the formation histo…
Resolved Spectroscopy of a Gravitationally Lensed L* Lyman-break Galaxy at z~5
A. M. Swinbank, R. G. Bower, G. P. Smith +6
By combining HST imaging with optical (VIMOS) and near-infrared (SINFONI) integral field spectroscopy we exploit the gravitational potential of a massive, rich cluster at z=0.9 to…
Star Formation in AEGIS Field Galaxies since z=1.1 : The Dominance of Gradually Declining Star Formation, and the Main Sequence of Star-Forming Galaxies
K. G. Noeske, B. J. Weiner, S. M. Faber +26
We analyze star formation (SF) as a function of stellar mass (M*) and redshift z in the All Wavelength Extended Groth Strip International Survey (AEGIS). For 2905 field galaxies, c…
Quantifying Substructure Using Galaxy-Galaxy Lensing in Distant Clusters
Priyamvada Natarajan, Jean-Paul Kneib, Ian Smail +1
We present high-resolution mass reconstructions for five massive cluster-lenses spanning a redshift range from z = 0.18 - 0.57 utilizing archival Hubble Space Telescope data and ap…
The Relationship between Stellar and Halo Masses of Disk Galaxies at z = 0.2 - 1.2
Christopher J. Conselice, Kevin Bundy, Richard S. Ellis +2
We present the results of a study to determine the co-evolution of the virial and stellar masses for a sample of 83 disk galaxies between redshifts z = 0.2 - 1.2. The virial masses…
