H.E.S.S. detection and multi-wavelength study of the $z\sim$ 1 blazar PKS 0346$-$27

H. E. S. S. collaboration

PKS 0346-27 is a Low Synchrotron Peaked (LSP) blazar at redshift 0.991. The very-high-energy (VHE, E > 100 GeV) spectra of blazars are always affected by $\gamma \gamma$ absorption by the Ext…
