distances and redshiftsThe Tully–Fisher relationship (TFR) has been shown to have a relatively small observed scatter of ±0.35 mag implying an intrinsic scatter < ±0.30 mag. However, when the TFR is calibrated from distances derived from the Hubble relation for field galaxies scatter is ...
We derive a direct general map from the luminosity distance D(z) to the inhomogeneous matter distribution M(r) in the Lemaitre-Tolman-Bondi (LTB) cosmology and compute several examples. One of our examples explicitly demonstrates that it is possible to tune the LTB cosmological solution to ...
The Hubble relationship be-comes 'photons of light from a galaxy twice as far away, make twice as many interactions with the electrons in the plasma of IG space, lose twice as much energy and undergo twice the redshift.' A relationship between redshift and distance is found and, using ...
empirical models for the relationship between z and the observed spectral index between 1.4 and 350 GHz, α 350 1.4 , based on the spectral energy distributions (SEDs) of Arp 220 and M82, plus semi-analytic models based on the equations in Condon (1992), assuming ...
We concentrate on the nonlinear relationship between the UV and X-ray luminosities of quasars serving as standard candles across a redshift range spanning 0.009<z<7.5. In Sect. 2, we introduce all the cosmological models. We give the methodology and observation datasets including QSO plus two ...
Light is redshifted and the greater the z, the further the spectral shift is to the left. Is there a point at which low-frequency EM (radio/micro waves) shifts below the spectra and disappear? The real question - Is there a z, and thus an implied distance, at which the highest ener...
Distance—redshift relationship function of log(z) from Hewitt and Burbidge.32 By plotting log(1+z)—which is related to the wavelength of the photons and thus the energy—the scatter in the points is greatly reduced. The data shows a better correlation with the loss of energy due to the...
The Hubble law is a linear relationship between distance and redshift which assumes that the rate of expansion of the universe is constant. However, when the universe was 'younger,' the expansion rate, and therefore the Hubble 'constant,' was larger than it is today. For more distant galaxie...
Accordingly, the The duality relationship between the KR field strength and the axion ξ (∂ [µ B νλ] = ǫ σ µνλ ∂ σ ξ) implies the exponential suppression in the ξ-field as well. In a static spherically symmetric spacetime the maximum 4-dim effective KR fi...
