The Stromlo-APM Redshift Survey. IV. The Redshift Catalog

The Astrophysical Journal Supplement Series, 1996
The Stromlo-APM Redshift Survey consists of 1797 galaxies with {ital b}{sub {ital J}}{le}17.15 selected randomly, at a rate of 1 in 20 from automated plate measurement (APM) scans. The survey covers a solid angle of 1.3 sr (4300 deg{sup 2}) in the south Galactic cap. Redshifts have been measured for 1790 (99.6{percent}) of the galaxies.

The MOST Hosts Survey: Spectroscopic Observation of the Host Galaxies of ∼40,000 Transients Using DESI

The Astrophysical Journal Supplement Series
We present the Multi-Object Spectroscopy of Transient (MOST) Hosts survey. The survey is planned to run throughout the 5 yr of operation of the Dark Energy Spectroscopic Instrument (DESI) and will generate a spectroscopic catalog of the hosts of most ...

Probabilistic Forward Modeling of Galaxy Catalogs with Normalizing Flows

The Astronomical Journal
Evaluating the accuracy and calibration of the redshift posteriors produced by photometric redshift (photo- z ) estimators is vital for enabling precision cosmology and extragalactic astrophysics with modern wide-field photometric surveys.

JWST Discovery of a High-redshift Tidal Disruption Event Candidate in COSMOS-Web

The Astrophysical Journal
The rates and properties of tidal disruption events (TDEs) provide valuable insights into their host galaxy central stellar densities and the demographics of their central supermassive black holes. TDEs have been observed only at low redshifts ( z  ≲ 1),

Characterizing and Propagating Modeling Uncertainties in Photometrically-Derived Redshift Distributions

, 2011
The uncertainty in the redshift distributions of galaxies has a significant potential impact on the cosmological parameter values inferred from multi-band imaging surveys.

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 Massive and Distant Clusters of WISE Survey 2: Equatorial First Data Release

The Astrophysical Journal
The Massive and Distant Clusters of WISE Survey 2 (MaDCoWS2) is a new survey designed as the successor of the original MaDCoWS survey. MaDCoWS2 improves upon its predecessor by using deeper optical and infrared data and a more powerful detection ...

A Holistic Exploration of the Potentially Recoverable Redshift Information of Stage IV Galaxy Surveys

The Astrophysical Journal
Extragalactic science and cosmology with Stage IV galaxy surveys will rely almost exclusively on redshift measurements derived solely from photometry, which are subject to systematic and statistical uncertainties with numerous analysis choices.
