Photo-z Estimation with Normalizing Flow

The Astrophysical Journal
Accurate photometric redshift (photo- z ) estimation is a key challenge in cosmology, as uncertainties in photo- z directly limit the scientific return of large-scale structure and weak lensing studies, especially in upcoming Stage IV surveys.

Galaxy redshift surveys selected by neutral hydrogen using FAST

, 2008
We discuss the possibility of performing a substantial spectroscopic galaxy redshift survey selected via the 21cm emission from neutral hydrogen using the Five-hundred metre Aperture Spherical Telescope (FAST) to be built in China.

Submillimeter Surveys at High Redshift [PDF]

Highlights of Astronomy, 2002
AbstractDeep submillimeter (submm) surveys offer an unobscured view of dust-enshrouded star formation or AGN activity at high red-shifts. SCUBA observations above 2 mJy have resolved 20 – 30% of the far-infrared (FIR) background into discrete sources and have revealed the existence of a distant population of galaxies with properties similar to those of

A Photometric Redshift Catalogue of Galaxies from the DESI Legacy Imaging Surveys DR10

The Astronomical Journal
The large-scale measurement of galaxy redshifts holds significant importance for cosmological research, as well as for understanding the formation and evolution of galaxies. This study utilizes a known sample obtained by cross-correlating the Dark Energy

A test for the redshift dependence of $$\sigma _8$$ σ 8 using $$f\sigma _8$$ f σ 8 measurements

European Physical Journal C: Particles and Fields
We search for a redshift dependence of $$\sigma _8^0$$ σ 8 0 using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of $$\Lambda $$ Λ CDM.

A Subaru galaxy redshift survey: WFMOS survey

Journal of Physics: Conference Series, 2008
A planned galaxy redshift survey with the Subaru 8.2m telescope, the WFMOS survey, offers a unique opportunity for probing detailed properties of large-scale structure formation in the expanding universe by measuring clustering strength of galaxy distribution as a function of distance scale and redshift.

Spatially Resolved Modeling of Galactic Hα Emission for Galaxy Clustering

The Astrophysical Journal
Near-infrared spectroscopic surveys target high-redshift emission-line galaxies (ELGs) to probe cosmological scenarios. Understanding the clustering properties of ELGs is essential to derive optimal constraints.
