Cosmology with photometric redshift surveys [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2005
We explore the utility of future photometric redshift imaging surveys for delineating the large-scale structure of the Universe, and assess the resulting constraints on the cosmological model. We perform two complementary types of analysis: (1) We quantify the statistical confidence and the accuracy with which such surveys will be able to detect and ...

Bayesian inference from photometric redshift surveys [PDF]

open access: yes, 2011
We show how to enhance the redshift accuracy of surveys consisting of tracers with highly uncertain positions along the line of sight. This increased redshift precision is achieved by imposing an isotropy and two-point correlation prior in a Bayesian ...

Recovering the real-space correlation function from photometric redshift surveys [PDF]

open access: yes, 2008
Measurements of clustering in large-scale imaging surveys that make use of photometric redshifts depend on the uncertainties in the redshift determination.

MAPPING THE GALAXY COLOR–REDSHIFT RELATION: OPTIMAL PHOTOMETRIC REDSHIFT CALIBRATION STRATEGIES FOR COSMOLOGY SURVEYS [PDF]

open access: yes, 2015
Calibrating the photometric redshifts of ≳109 galaxies for upcoming weak lensing cosmology experiments is a major challenge for the astrophysics community.

Cosmology with large galaxy redshift surveys

open access: yesAIP Conference Proceedings, 2012
Galaxy redshift surveys are a major tool to address the most challenging cosmological problems facing cosmology, like the nature of dark energy and properties dark matter. The same observations are useful for a much larger variety of scientific applications, from the study of small bodies in the solar system, to properties of tidal streams in the Milky

Forecasting cosmological constraints from redshift surveys [PDF]

open access: yes, 2008
Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on the expansion rate of the Universe and our theory of gravity. In this paper,

Measuring Galaxy Environments with Deep Redshift Surveys [PDF]

open access: yes, 2005
We study the applicability of several galaxy environment measures (nth-nearest neighbor distance, counts in an aperture, and Voronoi volume) within deep redshift surveys.

SHELS: TESTING WEAK-LENSING MAPS WITH REDSHIFT SURVEYS [PDF]

open access: yes, 2009
Weak-lensing surveys are emerging as an important tool for the construction of “mass-selected” clusters of galaxies. We evaluate both the efficiency and completeness of a weak-lensing selection by combining a dense, complete redshift survey, the ...
