The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift measurements and the survey data base.

Noncosmological redshifts [PDF]
Space Science Reviews, 1977 L’introduction de lignes d’univers brisées dans la théorie de la gravitation de Hoyle et Narlikar permet de rendre compte de la création de matière. Cette matière qui se compose de masses inertielles plus petites se manifeste par des décalages spectraux vers le rouge anormaux.

Puzzlement about thermal redshift [PDF]
Physics Letters A, 1997 Discussed is the classical theoretical description of the experimentally established thermal redshift of spectral lines. Straightforward calculation of the observable spectrum from a canonical ensamble of monochromatic radiators yileds overall blueshift ...

On estimating redshift and luminosity distributions in photometric redshift surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 The luminosity functions of galaxies and quasars provide invaluable information about galaxy and quasar formation. Estimating the luminosity function from magnitude limited samples is relatively straightforward, provided that the distances to the objects

The physical properties of star-forming galaxies in the low-redshift universe [PDF]
, 2003 We present a comprehensive study of the physical properties of ∼ 10 5 galaxies with measurable star formation in the Sloan Digital Sky Survey (SDSS). By comparing physical information extracted from the emission lines with continuum properties, we build ...

Coelenterazine Indicators for the Specific Imaging of Human and Bovine Serum Albumins
Sensors, 2023 Albumin assays in serum are important for the prognostic assessment of many life-threatening diseases, such as heart failure, liver disease, malnutrition, inflammatory bowel disease, infections, and kidney disease. In this study, synthetic coelenterazine

Relativistic redshift of the star S0-2 orbiting the Galactic Center supermassive black hole [PDF]
Science, 2019 Gravitational redshift in the Galactic Center General relativity predicts that light emitted by an object in a strong gravitational field—for example, close to a black hole—should be shifted to longer wavelengths.

A Modified Vilsmeier–Haack Strategy to Construct β-Pyridine-Fused 5,10,15,20-Tetraarylporphyrins
SynOpen, 2020 A modified Vilsmeier–Haack strategy has been developed to construct a novel series of π-extended nickel(II) or copper(II) complexes of 2-chloro-3-formyl- and 3-formylpyrido[2,3-b]porphyrins from 2-acetamido-meso-tetraarylporphyrins. After chromatographic
