98 p, 1.4 MB Study of the Gamma Ray Horizon with MAGIC as a new method to perform cosmological measurements / Blanch Bigas, Oscar ; Martinez Rodriguez, Manel, dir. (Institut de Física d'Altes Energies)
Les mesures precises de la disminució extrínseca de l'espectre, que és a causa de l'absorció de raigs de gamma en el fons extragalàctic difús, de Nuclis Galàctics Actius distribuïts en una rang de redshift gran porten a una tècnica nova per realitzar mesures de les densitats cosmològiques. [...]
Precise measurements of the extrinsic cutoff, which is due to the absorption of gamma-rays in the diffuse extragalactic background, of Active Galactic Nuclei distributed in a large redshift range lead to a new technique to perform measurements of the cosmological densities. [...]
