Redshift evolution of clustering [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1997
We discuss how the redshift dependence of the observed two-point correlation function of various classes of objects can be related to theoretical predictions. This relation involves first a calculation of the redshift evolution of the underlying matter correlations.

Evolution of the AGN UV luminosity function from redshift 7.5 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
Determinations of the ultraviolet (UV) luminosity function of active galactic nuclei (AGN) at high redshifts are important for constraining the AGN contribution to reionization and understanding the growth of supermassive black holes.

О красном смещении спектров галактик [PDF]

open access: yesФилософия и космология, 2015
It is observed the spherical model of the Metagalaxy (Metagalaxy here is the observed part of the Universe) with the observer in the center of the sphere.

Spherical Redshift Distortions [PDF]

open access: yes, 1995
Peculiar velocities induce apparent line of sight displacements of galaxies in redshift space, distorting the pattern of clustering in the radial versus transverse directions.

Detecting Helium Reionization with Fast Radio Bursts

open access: yes, 2020
Fast radio bursts (FRB) probe the electron density of the universe along the path of propagation, making high redshift FRB sensitive to the helium reionization epoch.

Hubble Parameter and Baryon Acoustic Oscillation Measurement Constraints on the Hubble Constant, the Deviation from the Spatially Flat ΛCDM Model, the Deceleration–Acceleration Transition Redshift, and Spatial Curvature [PDF]

open access: yes, 2017
We compile a complete collection of reliable Hubble parameter H(z) data to redshift z ≤ 2.36 and use them with the Gaussian Process method to determine continuous H(z) functions for various data subsets.

Gravitational Redshift Test Using Eccentric Galileo Satellites. [PDF]

open access: yesPhysical Review Letters, 2018
We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of general relativity and all metric theories of gravitation.

Redshift Weights for Baryon Acoustic Oscillations : Application to Mock Galaxy Catalogs [PDF]

open access: yes, 2016
Large redshift surveys capable of measuring the Baryon Acoustic Oscillation (BAO) signal have proven to be an effective way of measuring the distance-redshift relation in cosmology. Building off the work in Zhu et al.

Evolution of Interstellar Medium, Star Formation, and Accretion at High Redshift [PDF]

open access: yes, 2017
ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z = 0.3 to 4.5 in the COSMOS field.
