Frequency Decay through Electromagnetic Radiation Absorption and Re Emission by Inter Galactic Dark Matter as an Alternate Explanation for the Hubble Constant
... There is an alternate cause for the decay rate defined by Edwin Hubble’s Cosmological Constant Theory. It can be proposed because inward motion is observed in the local Galaxies||Star groups around the Milky Way. ...

First measurement of the Hubble Constant from a dark standard siren using the Dark Energy Survey galaxies and the LIGO/Virgo binary–black-hole merger GW170814
... We produce alternative photo-z estimates with another machine-learning code, ANNZ2 ( Sadeh et al. 2016 ) . This allows us to test the impact of the correction applied to the DNF errors on the posterior of the ...

A New Model of the Gravitational Lens 0957+561 and a Limit on the Hubble Constant
... The factor (1 − κ) in equation [4-14] arises because of a degeneracy in lens models discovered by Falco et al. (1985) and Gorenstein et al. (1988b). These authors showed that any lens model can be modified by reducing ...
