Extended Data Fig. 10: Comparison of RS Oph to other Fermi-LAT-detected novae.
From: Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Spectra of other Fermi-LAT-detected novae are shown in the top panel. Gamma-ray spectra of V407 Cyg (middle panel) and V339 Del (bottom panel) compared to the measured (red) and scaled (gray) RS Oph gamma-ray spectra. Blue triangles and arrows correspond to Fermi-LAT measurements and upper limits of V407 Cyg (top) and V339 Del (bottom). Red squares are the Fermi-LAT spectrum of RS Oph and red circles the MAGIC one. Gray squares are the Fermi-LAT scaled spectrum of RS Oph and gray circles the MAGIC one. Cyan arrows correspond to the VERITAS (V407 Cyg) and MAGIC (V339 Del) upper limits. The dashed blue lines correspond to the best-fit using a single power-law for the Fermi-LAT data. The dotted blue lines correspond to the best-fit using a power-law with an exponential cut-off for the Fermi-LAT data. Data taken from13,14,15,16,68. Error bars represent 1-sigma statistical uncertainties in the data points.
