Nucleus in astronomy
Web2.2 Active galactic nuclei A large fraction of the known high-energy sources is represented by AGNs, most of them belonging to the blazar class and characterized by jet-like emission and broadband spectra peaking at gamma rays and between radio and X-ray. Webenergy comes from the full charge of the nuclei, neglecting any cancellation coming from electrons of opposite charge “screening” the nuclear charges. To see how this compares to the thermal energy, i.e. to compute the ratio E/k BT, ideally we would check at every point in the star, since both ρ and k BT change with position.
