Red shifts of photons and massive particles

open access: yes
Red‒shift phenomena were attributed to different mechanisms: Doppler red shifts and gravitational red shifts. Here, based on Space Motion Theory, a common mechanism of red shifts is concluded into a formula: 1+z=(Ec/Ec’)(Eqr/Eqs), where z represents the value of a red shift; (Ec/Ec’), named the photonic red shift, signifies the energy change of the ...

On the red-shift of quasars

open access: yes, 1969
In a recent note, the idea was proposed that red-shift excess observed in quasars, could be interpreted as due to direct Compton effect caused by relativistic electrons. The purpose of the present paper is to give a physical basis justifying that, for which the Compton reddening formula and the cross-section of the process is needed. In order to derive
