Probing the large-scale structure of the universe with future galaxy redshift surveys [PDF]
, 1999 Several projects are currently underway to obtain large galaxy redshift surveys over the course of the next decade. The aim of this thesis is to study how well the resultant three-dimensional maps of the galaxy distribution will be able to constrain the ...

Deep Spectroscopy with DESI for Photometric Redshift Training and Calibration
The Astronomical JournalDeep spectroscopic samples can improve photometric redshift (photo- z ) estimates and reduce uncertainties on redshift distributions. Such improvements can increase the cosmological constraining power of large imaging-based experiments such as the Vera C.

Topology and geometry of the CfA2 redshift survey [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 We analyse the redshift space topology and geometry of the nearby Universe by computing the Minkowski functionals of the Updated Zwicky Catalogue (UZC). The UZC contains the redshifts of almost 20,000 galaxies, is 96% complete to the limiting magnitude m_Zw=15.5 and includes the Center for Astrophysics (CfA) Redshift Survey (CfA2).

The clustering of galaxies in hierarchical galaxy formation models [PDF]
, 2010 Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

The luminosity function of Lyα emitters at 2.3 < z < 4.6 from integral-field spectroscopy [PDF]
, 2005 We have used Visible MultiObject Spectrograph Integral-Field Unit observations centred on a radio galaxy at z= 2.9 to search for Lyα emitters within a comoving volume of ∼104 Mpc3 .

, 2006 The DEIMOS spectrograph is nearing completion in the UC Lick shops and will be delivered to the Keck Observatory in 2001. Once it is operational, a team of astronomers will initiate DEEP2, a major redshift survey of galaxies that will consume approximately 120 nights at the Keck Observatory over a three year period.

Redshift sensitivities of dark energy surveys
Physical Review D, 2006 Great uncertainty surrounds dark energy, both in terms of its physics, and the choice of methods by which the problem should be addressed. Here we quantify the redshift sensitivities offered by different techniques. We focus on the three methods most adept at constraining w, namely supernovae, cosmic shear, and baryon oscillations.

THE DEEP2 GALAXY REDSHIFT SURVEY: DESIGN, OBSERVATIONS, DATA REDUCTION, AND REDSHIFTS [PDF]
The Astrophysical Journal Supplement Series, 2013 We describe the design and data sample from the DEEP2 Galaxy Redshift Survey, the densest and largest precision-redshift survey of galaxies at z ~ 1 completed to date. The survey has conducted a comprehensive census of massive galaxies, their properties, environments, and large-scale structure down to absolute magnitude M_B = -20 at z ~ 1 via ~90 ...

The effect of the environment on the evolution of galaxy colours [PDF]
, 2006 In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...
