Measuring Galaxy Environments with Deep Redshift Surveys [PDF]
, 2005 We study the applicability of several galaxy environment measures (n^th-nearest-neighbor distance, counts in an aperture, and Voronoi volume) within deep redshift surveys.

Constraints onOmega from the IRAS Redshift Surveys [PDF]
, 1994 We measure the anisotropy of the redshift-space power spectrum in the 1.2-Jy and QDOT redshift surveys of IRAS-selected galaxies. On large scales, this anisotropy is caused by coherent peculiar motions, and gravitational instability theory predicts a ...

SHELS: Testing Weak Lensing Maps with Redshift Surveys [PDF]
, 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 ...

Topological Approach to Void Finding Applied to the SDSS Galaxy Map [PDF]
The Astrophysical JournalThe structure of the low redshift Universe is dominated by a multiscale void distribution delineated by filaments and walls of galaxies. The characteristics of voids, such as morphology, average density profile, and correlation function, can be used as ...

Cosmological inference from Bayesian forward modelling of deep galaxy redshift surveys [PDF]
Astronomy & Astrophysics, 2018 We present a large-scale Bayesian inference framework to constrain cosmological parameters using galaxy redshift surveys, via an application of the Alcock-Paczyński (AP) test.

Redshift Surveys With 2DF [PDF]
Highlights of Astronomy, 1998 This IAU Joint Discussion proposes to address the subject of redshift surveys in the 21st century. This paper, however, deals with two major new redshift surveys that those involved sincerely hope will be completed in the 20th century. Nonetheless, these surveys are relevant to the topic of the meeting, as they clearly foreshadow the scope and style of
