The FLAMINGOS Extragalactic Survey
Richard J. Elston, Anthony H. Gonzalez, Eric McKenzie +12
Using the Florida Multi-object Imaging Near-IR grism Observational Spectrometer (FLAMINGOS), we have conducted the FLAMINGOS Extragalactic Survey (FLAMEX), a deep imaging survey co…
Constraining Dark Energy with the Dark Energy Survey: Theoretical Challenges
James Annis, Sarah Bridle, Francisco J. Castander +14
The Dark Energy Survey (DES) will use a new imaging camera on the Blanco 4-m telescope at CTIO to image 5000 square degrees of sky in the South Galactic Cap in four optical bands,…
Dark Energy Studies: Challenges to Computational Cosmology
James Annis, Francisco J. Castander, August E. Evrard +12
The ability to test the nature of dark mass-energy components in the universe through large-scale structure studies hinges on accurate predictions of sky survey expectations within…
Effects of Mergers and Core Structure on the Bulk Properties of Nearby Galaxy Clusters
Timothy B. O'Hara, Joseph J. Mohr, John J. Bialek +1
We use morphological measurements and the scatter of clusters about observed and simulated scaling relations to examine the impact of merging and core-related phenomena on the stru…
An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
