Cosmology with photometric redshift surveys

Monthly 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 the following two complementary types of analysis.

Forecasting cosmological constraints from redshift surveys

Monthly Notices of the Royal Astronomical Society, 2009
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,

Redshift Surveys Of Galaxies

Annual Review of Astronomy and Astrophysics, 1991
The desire to map the universe in three dimensions has provided the main stimulus for the growth of one of the most successful industries in the history of modern astronomy: the surveying of galaxy redshifts. After the pioneering work of Slipher, Humason, Mayall, and others in the earlier half of the century, the completion of the redshift data base ...

Using galaxy redshift surveys to detect gravitationally lensed quasars [PDF]

Monthly Notices of the Royal Astronomical Society, 2000
Gravitationally lensed quasars can be discovered as a by-product of galaxy redshift surveys. Lenses discovered spectroscopically in this way should require less observational effort per event than those found in dedicated lens surveys.

A Redshift Survey in the Linx Gemini Region

Advances in Space Research, 1984
The study of the redshift distribution of a complete sample of galaxies brighter than 14.5 mph has been performeded over an area encompassing about 1800 square degrees in Linx and Gemini. The main result is the discovery of a new filament of galaxies in Gemini, at a radial velocity of 4800 km/s, mainly composed of spirals.

The Durham/UKST Galaxy Redshift Survey

1991
We are currently engaged in a long-term project to make a redshift survey of ~ 4000 galaxies based on the Durham/ROE Southern Galaxy Catalogue (Collins et al., 1988) which is a COSMOS survey of the 2D distribution of b j > 20.5m galaxies over 60 UK Schmidt Telescope (UKST) fields.

Surveys of Galaxy Redshifts

1992
Recent advances in spectrometers at both optical and radio wavelengths have tremendously increased the efficiency with which surveys of the redshifts (Doppler shifts) of large numbers of galaxies can be conducted. Such surveys can follow quite different strategic and technical directions, covering with different degrees of completeness one-, two-, or ...
