| 内容記述 | The first X-ray spectrum of a classical Seyfert 2 galaxy, NGC 1068, measured by the Einstein Observatory, is presented. The small soft X-ray luminosity of about 9 x 10 to the 41st ergs/s, the lack of variability, and the Compton temperature of less than 10 to the 6th K are all consistent with the model of Antonucci and Miller (1985); these authors have suggested that NGC 1068 contains a hidden Seyfert 1 nucleus seen indirectly through the electron scattering. However, the steep spectral slope (alpha = 2.0 + or - 0.3) distinguishes the NGC 1068 from the vast majority of Seyfert 1 galaxies. |
