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.

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 2MASS Redshift Survey in the Zone of Avoidance [PDF]
The Astrophysical Journal Supplement Series, 2019 Abstract The Two Micron All-Sky Survey (2MASS) Redshift Survey was started two decades ago with the goal of mapping the three-dimensional distribution of an all-sky flux-limited (K s < 11.75 mag) sample of ∼45,000 galaxies.

All‐Cellulose‐Based Photonic Glitters
Advanced Functional Materials, EarlyView.Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

The AAO 2DF QSO Redshift Survey [PDF]
Symposium - International Astronomical Union, 1999 The study of large-scale structure through QSO clustering provides a potentially powerful route to determining the fundamental cosmological parameters of the Universe (see Croom & Shanks 1996). Unfortunately, previous QSO clustering studies have been limited by the relatively small sizes of homogeneous QSO catalogues that have been available ...

Photo-zSNthesis: Converting Type Ia Supernova Lightcurves to Redshift Estimates via Deep Learning
The Astrophysical Journal, 2023 Upcoming photometric surveys will discover tens of thousands of Type Ia supernovae (SNe Ia), vastly outpacing the capacity of our spectroscopic resources.

HerMES: A Statistical Measurement of the Redshift Distribution of Herschel-SPIRE Sources Using the Cross-correlation Technique [PDF]
, 2012 The wide-area imaging surveys with the Herschel Space Observatory at submillimeter (sub-mm) wavelengths have now resulted in catalogs of the order of one-hundred-thousand dusty, starburst galaxies.
