Description: ‚EúDoppler boosting‚EĚ is a well-known relativistic effect that alters the apparent luminosity of approaching radiation sources. ‚EúDoppler de-boosting‚EĚ is the same relativistic effect observed but for receding light sources (e.g. relativistic jets of AGN and GRB). ‚EúDoppler boosting‚EĚ alters the apparent luminosity of approaching light sources to appear brighter, while ‚EúDoppler de-boosting‚EĚ alters the apparent luminosity of receding light sources to appear fainter. While ‚EúDoppler de-boosting‚EĚ has been successfully accounted for and observed in relativistic jets of AGN, it was ignored in the establishment of Standard candles for cosmological distances. A Standard Candle adjustment of Z>0.1 is necessary for ‚EúDoppler de-boosting‚EĚ, otherwise we would incorrectly assume that Standard Candles appear dimmer, not because of ‚EúDoppler de-boosting‚EĚ but because of the excessive distance, which would affect the entire Standard Candles ladder at cosmological distances. The ratio between apparent (L) and intrinsic (Lo) luminosities as a function of the redshift Z and spectral index IĪ is given by the formula ‚Ą≥(Z) = L/Lo=(Z+1)IĪ -3 and for Type Ia supernova appears as ‚Ą≥(Z) = L/Lo=(Z+1)-2. ‚EúDoppler de-boosting‚EĚ may also explain the anomalously low luminosity of objects with a high Z without the introduction of an accelerated expansion of the Universe and Dark Energy.
