Creating Spectral Templates from Multicolor Redshift Surveys [PDF]

open access: bronze, 2000
Understanding how the physical properties of galaxies (e.g. their spectral type or age) evolve as a function of redshift relies on having an accurate representation of galaxy spectral energy distributions.

Forward Modeling of Galaxy Populations for Cosmological Redshift Distribution Inference

open access: yesThe Astrophysical Journal Supplement Series, 2023
We present a forward-modeling framework for estimating galaxy redshift distributions from photometric surveys. Our forward model is composed of: a detailed population model describing the intrinsic distribution of the physical characteristics of galaxies,

The miniJPAS survey: Photometric redshift catalogue [PDF]

open access: yesAstronomy & Astrophysics, 2021
MiniJPAS is a ∼1 deg2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS). Full coverage of the 3800–9100 Å range with 54 narrow-band filters, in combination with 6 optical broad-band filters, allows for extremely ...

A Southern Photometric Quasar Catalog from the Dark Energy Survey Data Release 2

open access: yesThe 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

The Spectroscopic Data Processing Pipeline for the Dark Energy Spectroscopic Instrument

open access: yesThe 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

Deconstructing the neutrino mass constraint from galaxy redshift surveys [PDF]

open access: yes, 2017
The total mass of neutrinos can be constrained in a number of ways using galaxy redshift surveys. Massive neutrinos modify the expansion rate of the Universe, which can be measured using baryon acoustic oscillations (BAOs) or the Alcock-Paczynski (AP ...

Lensing convergence and the neutrino mass scale in galaxy redshift surveys [PDF]

open access: yes, 2016
We demonstrate the importance of including the lensing contribution in galaxy clustering analyses with large galaxy redshift surveys. It is well known that radial cross-correlations between different redshift bins of galaxy surveys are dominated by ...

A Redshift Survey of IRAS Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1988
We have completed a redshift survey of approximately 2200 IRAS galaxies, flux limited at 60μ. The survey covers 76% of the sky and has a characteristic depth of ≈ 6000 km s−1, making it ideal for large scale structure studies requiring whole sky coverage.

Will kinematic Sunyaev-Zel'dovich measurements enhance the science return from galaxy redshift surveys? [PDF]

open access: yes, 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
