Three-Dimensional Identification and Reconstruction of Galaxy Systems within Deep Redshift Surveys
Christian Marinoni, Marc Davis, Jeffrey A. Newman +1
We have developed a new geometrical method for identifying and reconstructing a homogeneous and highly complete set of galaxy groups in the next generation of deep, flux-limited re…
Chandra Detection of a TypeII Quasar at z=3.288
Daniel Stern, Edward C. Moran, Alison L. Coil +16
We report on observations of a TypeII quasar at redshift z=3.288, identified as a hard X-ray source in a 185 ks observation with the Chandra X-ray Observatory and as a high-redshif…
Spectral Reduction Software for the DEEP2 Redshift Survey
Christian Marinoni, Marc Davis, Alison L. Coil +1
The DEEP2/DEIMOS redshift survey, which will begin observing in the Spring of 2002, will gather high quality spectra on ~60000 galaxies in order to study the evolution of the prope…
3D Identification and Reconstruction of z~1 Clusters: Prospects for the DEEP2 Redshift Survey
Christian Marinoni, Marc Davis, Jeffrey A. Newman +1
We have developed a geometrical method based on 3D Voronoi polyhedra and Delaunay tessellation for identifying and reconstructing clusters of galaxies in the next generation of dee…
Measuring the Cosmic Equation of State with Galaxy Clusters in the DEEP2 Redshift Survey
Jeffrey A. Newman, Christian Marinoni, Alison L. Coil +1
The abundances of groups and clusters of galaxies are expected to have changed substantially since high redshift, with the strength of this evolution dependent upon fundamental cos…
Measuring the Cosmic Equation of State with Counts of Galaxies II: Error Budget for the DEEP2 Redshift Survey
Jeffrey A. Newman, Marc Davis
In a previous paper, we described a new variant on the classical dN/dz test which could be performed using upcoming redshift surveys. By observing the velocity function of galaxies…
Galaxy Correlation Statistics of Mock Catalogs for the DEEP2 Survey
Alison L. Coil, Marc Davis, Istvan Szapudi
The DEEP2 project will obtain redshifts for ~60,000 galaxies between z~0.7-1.5 in a comoving volume of 7 10^6 Mpc/h^3 for an LCDM universe. The survey will map four separate 2 by 0…
The Structure of Dark Matter Halos in an Annihilating Dark Matter Model
Matthew W. Craig, Marc Davis
The inability of standard non-interacting cold dark matter (CDM) to account for the small scale structure of individual galaxies has led to the suggestion that the dark matter may…
A Composite Seyfert 2 X-ray Spectrum: Implications for the Origin of the Cosmic X-ray Background
Edward C. Moran, Laura E. Kay, Marc Davis +2
We present a composite 1-10 keV Seyfert 2 X-ray spectrum, derived from ASCA observations of a distance-limited sample of nearby galaxies. All 29 observed objects were detected. Abo…
Mining the Sky with Redshift Surveys
Marc Davis, Jeffrey Newman
Since the late 1970's, redshift surveys have been vital for progress in understanding large-scale structure in the Universe. The original CfA redshift survey collected spectra of 2…
