1) did Hubble's original linear relationship between red shift and distance take into account gravitational slowing of the rate of expansion? By this I mean, would a plot of red shift on the y-axis and distance on the x-axis be pulled slightly below a straight line (with negative slope)...
This gives us the opportunity to determine the average electron number density in intergalactic space and thus test New Tired Light predictions. Here, in an alternative cosmology, the universe is static and redshifts are produced by an interaction between photons and the electrons in the ...

A quantitative spectral analysis of 24 A supergiants in the Sculptor Group spiral galaxy NGC 300 at a distance of 1.9 Mpc is presented. A new method is introduced to analyze low resolution (~5 AE) spectra, which yields metallicities accurate to 0.2 dex including the uncertainties arising from...

The statistical significance increases if we additionally remove non-members using the Sloan Digital Sky Survey photometric redshift information (~2.6蟽 and 99.3%). Our results suggest three possible scenarios: (1) vestiges of infallen groups, (2) dwarf capturing, and (3) tidal tearing of ...
The results of Markov flux analysis indicate that the conformational differences between glow-type and flash-type mutants when combined with luciferin substrate CTZ mainly involve the helicity change of α7. The most representative conformation and active pocket distance analysis indicate that compared to...
