How is redshift used to measure distance
WebIn a recent paper [], some of us (NM, MP and VT) have shown how it is possible to use simultaneous multiwavelength (i.e. optical, X-ray, HE γ 𝛾 \gamma italic_γ, and VHE γ 𝛾 \gamma italic_γ) data to obtain a measure the Extragalactic Background Light (EBL).EBL is the integrated light produced and re-processed in all the history of the universe.
