A new derivation of the Hubble constant from $\gamma$-ray attenuation using improved optical depths for the Fermi and CTA era

A. Domínguez, P. Østergaard Kirkeberg, R. Wojtak +8

We present $\gamma$-ray optical-depth calculations from a recently published extragalactic background light (EBL) model built from multiwavelength galaxy data from the Hubble Space Tele…
