Performance of the Quasar Spectral Templates for the Dark Energy Spectroscopic Instrument
The Astronomical Journal, 2023 Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a fourfold increase in the number of known quasars.

The kinetic SZ tomography with spectroscopic redshift surveys [PDF]
, 2010 The kinetic Sunyaev Zel'dovich effect (kSZ) effect is a potentially powerful probe to the missing baryons. However, the kSZ signal is overwhelmed by various contaminations and the cosmological application is hampered by loss of redshift information due ...

Hydra — Centaurus: A Redshift Survey [PDF]
Symposium - International Astronomical Union, 1988 The survey consists of 2 samples : SAMPLE A, 85% complete to B(T) = 14.0 in the region between 10 and 14 Hours in R.A. and between −20 and −50 degrees in DEC., SAMPLE B, complete to B(0) = 14.5 in two regions one between R.A. 13 and 14 hours, DEC between −25 and −33, the other between 11 and 12 hours, DEC from −33 to −27.

How to falsify the GR+{Lambda}CDM model with galaxy redshift surveys [PDF]
, 2010 A wide range of models describing modifications to general relativity have been proposed, but no fundamental parameter set exists to describe them. Similarly, no fundamental theory exists for dark energy to parametrize its potential deviation from a ...

Tracing the sound horizon scale with photometric redshift surveys [PDF]
, 2010 We propose a new method for the extraction cosmological parameters using the baryon acoustic oscillation (BAO) scale as a standard ruler in deep galaxy surveys with photometric determination of redshifts.

The Unexplored Redshift Survey [PDF]
Publications of the Astronomical Society of the Pacific, 2001 Redshift surveys remain an important constraint on cosmological parameters and a key to characterizing the nature and evolution of the large‐scale distribution of galaxies. I discuss redshift surveys as a route to exploration of other issues associated with large‐scale structure including the low surface brightness universe and the links between star ...

Measuring the Universe with Galaxy Redshift Surveys [PDF]
, 2018 Galaxy redshift surveys are one of the pillars of the current standard cosmological model and remain a key tool in the experimental effort to understand the origin of cosmic acceleration. To this end, the next generation of surveys aim at achieving sub-percent precision in the measurement of the equation of state of dark energy $w(z)$ and the growth ...

The TOOT00 redshift survey of radio sources [PDF]
Astronomische Nachrichten, 2006 AbstractWe present first results from the study of the TOOT00 region consisting of 47 radio sources brighter than 100 mJy at 151 MHz. We have 81% spectroscopic redshift completeness. From theK‐zdiagram we deduce that the host galaxies are similar to ∼ 3L* passively evolved elliptical galaxies and thus estimate the redshifts of the 9 sources without a ...

Measuring Redshift-Space Distortions using Photometric Surveys [PDF]
, 2011 We outline how redshift-space distortions (RSD) can be measured from the angular correlation function w({\theta}), of galaxies selected from photometric surveys.
