The kinematic dipole in galaxy redshift surveys [PDF]
, 2017 In the concordance model of the Universe, the matter distribution—as observed in galaxy number counts or the intensity of line emission (such as the 21cm line of neutral hydrogen) —should have a kinematic dipole due to the Sun's motion relative to the ...

The redshift-space momentum power spectrum – I. Optimal estimation from peculiar velocity surveys [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Low redshift surveys of galaxy peculiar velocities provide a wealth of cosmological information. We revisit the idea of extracting this information by directly measuring the redshift-space momentum power spectrum from such surveys.

A Southern Photometric Quasar Catalog from the Dark Energy Survey Data Release 2
The Astrophysical Journal Supplement Series, 2022 We present a catalog of 1.4 million photometrically selected quasar candidates in the southern hemisphere over the ∼5000 deg ^2 Dark Energy Survey (DES) wide survey area. We combine optical photometry from the DES second data release (DR2) with available

Predicting Hα emission-line galaxy counts for future galaxy redshift surveys [PDF]
, 2017 Knowledge of the number density of Hα emitting galaxies is vital for assessing the scientific impact of the Euclid and Wide Field Infrared Survey Telescope (WFIRST) missions. In this work, we present predictions from a galaxy formation model, GALACTICUS,

The Spectroscopic Data Processing Pipeline for the Dark Energy Spectroscopic Instrument
The Astronomical Journal, 2023 We describe the spectroscopic data processing pipeline of the Dark Energy Spectroscopic Instrument (DESI), which is conducting a redshift survey of about 40 million galaxies and quasars using a purpose-built instrument on the 4 m Mayall Telescope at Kitt

Will kinematic Sunyaev-Zel'dovich measurements enhance the science return from galaxy redshift surveys? [PDF]
, 2016 Yes. Future CMB experiments such as Advanced ACTPol and CMB-S4 should achieve measurements with S/N of > 0.1 for the typical host halo of galaxies in redshift surveys. These measurements will provide complementary measurements of the growth rate of large

SHELS: COMPLETE REDSHIFT SURVEYS OF TWO WIDELY SEPARATED FIELDS [PDF]
, 2016 The Smithsonian Hectospec Lensing Survey (SHELS) is a complete redshift survey covering two well-separated fields (F1 and F2) of the Deep Lens Survey (DLS). Both fields are more than 94% complete to a Galactic extinction corrected R0 = 20.2.

Probing primordial non-Gaussianity with SKA galaxy redshift surveys: a fully relativistic analysis [PDF]
, 2014 The Square Kilometre Array (SKA) will produce spectroscopic surveys of tens to hundreds of millions of neutral hydrogen (H I) galaxies, eventually covering 30 000 deg2 and reaching out to redshift z≳2.
