Broadband SEDs of Kepler’s SNR (left) and Tycho’s SNR (right) with hadronic model fits. SED data points and butterfly plots for Kepler’s SNR as derived from H.E.S.S. and Fermi-LAT data are shown. Observations of Kepler’s SNR from the radio band to the X-ray band are from VLA (red filled °), Culgoora (red ▿), PAPER (red △), Molonglo (red °), Parkes (red ▫), NRAO (red ⋄), WMAP (red ⬠), RXTE (blue △), and Swift-BAT (blue ⋄).
