DESCRIPTION:Speakers: Fabian Schüssler (CEA-Saclay / Irfu)\nWhen very hig
 h-energy photons (VHE\, E>100 GeV) propagate over cosmological distances\,
  they interact with background light by pair production. Observations of s
 pectral features in the VHE band of extragalactic sources related to this 
 energy-dependent absorption process with the H.E.S.S. array of Cherenkov t
 elescopes allow measuring the spectral energy distribution (SED) of the ex
 tragalactic background light (EBL)\, otherwise very difficult to determine
 . Preliminary results on the determination of the SED of the EBL will be p
 resented\, based on the measurements of the energy spectra of blazars with
  H.E.S.S. . This model independent approach shows that the shape and overa
 ll normalization of the EBL SED is accessible.\n\nhttps://indico.icrr.u-to
