О красном смещении спектров галактик [PDF]
Философия 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.

Photometric redshifts and quasar probabilities from a single, data-driven generative model
, 2012 We describe a technique for simultaneously classifying and estimating the redshift of quasars. It can separate quasars from stars in arbitrary redshift ranges, estimate full posterior distribution functions for the redshift, and naturally incorporate ...

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.

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

A massive, quiescent galaxy at a redshift of 3.717 [PDF]
Nature, 2017 Finding massive galaxies that stopped forming stars in the early Universe presents an observational challenge because their rest-frame ultraviolet emission is negligible and they can only be reliably identified by extremely deep near-infrared surveys ...

The Problem of the Redshifts [PDF]
Symposium - International Astronomical Union, 1983 It is my intention in this brief paper to present once again some of the evidence which appears to show that a major contribution to the redshifts of QSOs and perhaps some galaxies is not associated with the expansion of the universe. The evidence continues to grow and it is of four kinds: (a)Evidence concerning galaxies with discrepant redshifts.(b ...

On the Anticorrelation between Duration and Redshift in Gamma-Ray Bursts
The Astrophysical Journal, 2023 For gamma-ray bursts (GRBs) with durations greater than two seconds (so-called long GRBs), the intrinsic prompt gamma-ray emission appears, on average, to last longer for bursts at lower redshifts.

, 2006 The redshift distribution of all 46,400 quasars in the Sloan Digital Sky Survey (SDSS) Quasar Catalog III, Third Data Release, is examined. Six Peaks that fall within the redshift window below z = 4, are visible.
