Abstract:

Abstract: The Crab nebula (CN) provides exceptionally bright non-thermal emission across the entire wavelength range from radio to the most energetic photons. The spatial and spectral structure of the non-thermal synchrotron emission is known in exceptional detail. The inverse Compton emission of the nebula has just recently been spatially resolved. In this work, we reexamine the inverse Compton (IC) scattering model for the unpulsed TeV emission from the Crab Nebula. We include for the first time in detail the spatial distribution of the seed photons coming from the thermal emission
