The Redshift Distribution of the TOUGH Survey [PDF]
, 2013 We present the redshift results from a Very Large Telescope program aimed at optimizing the legacy value of the Swift mission: to characterize a homogeneous, X-ray selected, sample of 69 GRB host galaxies. 19 new redshifts have been secured, resulting in

Probing cosmic voids with emission-line galaxies
Frontiers in Astronomy and Space SciencesIntroductionWe aim to provide forecasts for future line intensity mapping (LIM) observations and galaxy redshift surveys, focusing on the physical properties of low-density region of the cosmic web (voids).

European Physical Journal C: Particles and Fields, 2022 In this work, we discuss a new method to probe the redshift evolution of the gas depletion factor, i.e. the ratio by which the gas mass fraction of galaxy clusters is depleted with respect to the universal mean of baryon fraction.

Measuring Galaxy Environments with Deep Redshift Surveys
, 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.

Testing Weak Lensing Maps With Redshift Surveys: A Subaru Field
, 2012 We use a dense redshift survey in the foreground of the Subaru GTO2deg^2 weak lensing field (centered at $\alpha_{2000}$ = 16$^h04^m44^s$;$\delta_{2000}$ =43^\circ11^{\prime}24^{\prime\prime}$) to assess the completeness and comment on the purity of ...

The Inverse Redshift-Space Operator: Reconstructing Cosmological Density and Velocity Fields [PDF]
, 1999 We present the linear inverse redshift space operator which maps the galaxy density field derived from redshift surveys from redshift space to real space. Expressions are presented for observers in both the CMBR and Local Group rest frames.

The Astrophysical Journal, 2023 Euclid and the Roman Space Telescope (Roman) will soon use grism spectroscopy to detect millions of galaxies via their H α and [O iii ] λ 5007 emission. To better constrain the expected galaxy counts from these instruments, we use a vetted sample of 4239

1.4-GHz Luminosity Function of Galaxies from the Las Campanas Redshift Survey
, 1998 A preliminary 1.4 GHz RLF at redshift of about 0.14 is derived from the Las Campanas Redshift Survey (LCRS) and the NVSS radio data. No significant evolution has been found at this redshift in comparison to the 'local' RLF.Comment: 2 pages including 2 ...

The MUSE Hubble Ultra Deep Field Survey: II. Spectroscopic redshifts and comparisons to color selections of high-redshift galaxies [PDF]
, 2017 We have conducted a two-layered spectroscopic survey (1′ × 1′ ultra deep and 3′ × 3′ deep regions) in the Hubble Ultra Deep Field (HUDF) with the Multi Unit Spectroscopic Explorer (MUSE).

Simulating Continuum-based Redshift Measurement in the Roman’s High Latitude Spectroscopic Survey
The Astronomical JournalWe investigate the capability of the Nancy Grace Roman Space Telescope’s (Roman) Wide-Field Instrument G150 slitless grism to detect red, quiescent galaxies based on the current reference survey.
