Gamma Rays

MeV Radiation

• nuclear level diagram, decay scheme for ²⁶Al
• the sky at 511 keV here and here (Knodlseder+ 2005)
• the sky at 1.8 MeV and its origin

GeV and TeV Radiation

• the GeV sky as seen by Fermi
• supernova remnants Vela Jr and the Crab; and the Galactic plane in TeV photons (H.E.S.S.)

Finale

Galaxy Spectra

• average spectra of early type galaxies (LRGs; Eisenstein+ 2003)
