An absorption origin for the X-ray spectral variability of MCG – 6-30-15

Context. The Seyfert I galaxy MCG−6-30-15 shows one of the best examples of a broad “red wing” of emission in its X-ray spectrum at energies 2< E < 6.4 keV, commonly interpreted as being caused by relativistic ally-blurred reflection close to the event horizon of the black hole. Aims. We aim to test an alternative model in which absorption creat es the… CONTINUE READING
