Soft X-ray spectral variations of the narrow line Seyfert l galaxy Markarian 766 [PDF]
, 1999 The X-ray variability of the narrow-line Seyfert 1 galaxy Markarian 766 is studied using nine ROSAT PSPC data sets. The spectrum is well described by a power law combined with a blackbody (kT ∼ 70 eV) soft excess.
