On the cosmological distance and redshift between any two objects
نویسنده
چکیده
We discuss the problem of how to calculate the distance between two cosmological objects given their redshifts and angular separation on the sky. Although of a fundamental nature, this problem and its solution seem to lack a detailed description in the literature. We present a new variant of its solution and quantitatively assess the most commonly used approximation.

Using the Hubble Telescope to Determine the Split of a Cosmological Object’s Redshift into its Gravitational and Distance Parts
The Hubble Telescope should make it possible to separate the redshift of light from any cosmological object into that redshift due to the gravitational potential difference between the emission and reception points and that portion due the distance between these points by comparing the redshifts measured on the Earth’s surface to redshifts measured by the Hubble Telescope. This would allow a re...
متن کاملGravitational and Cosmological Spectral Shift with Remote Quantum States
A class of coordinate systems is found for Friedmann Cosmologies with local gravity such that it is possible to formulate quantum theory over astronomical and cosmological distances. When light from distance objects is treated as a quantum motion, new predictions are found for cosmological redshift and lensing. Good agreement is found between predictions and supernova redshifts for a closed Fri...
متن کاملRedshift in Absolute Space: Periodicity of Quasars and Other Cosmological Implica- tions
Assuming the existence of a preferred frame Σ (i.e., absolute space), we start from a Newtonian model based on the equivalence of gravitational work and inertial energy. Microscopic processes for the absorption and emission of photons lead to frequency shifts in absolute space. The resulting expressions contain both gravitational and velocity components, but—in contrast to the conventional mode...

This report is an update and extension of our paper accepted for publication in ApJ (arXiv:0802.4262). Since objects at the same redshift should have the same luminosity distance and the distance moduli of type Ia supernovae (SNe Ia) obtained directly from observations are completely cosmology independent, we obtain the distance modulus of a gammaray burst (GRB) at a given redshift by interpola...
متن کاملAnalytical Fit to the Luminosity Distance for Flat Cosmologies with a Cosmological Constant
Received ; accepted – 2 – ABSTRACT We present a fitting formula for the luminosity and angular diameter distances in cosmological models with pressureless matter, a cosmological constant and zero spatial curvature. The formula has a relative error of less than 0.4% for 0.2 < Ω 0 < 1 for any redshift, and a global relative error of less than 4% for any choice of parameters.
