| 内容記述 | Thirty-seven Seyfert galaxies have been observed with the Imaging Proportional Counter on the Einstein Observatory. X-ray emission from 20 Seyfert 1 galaxies, three of which have been previously detected, and from four Seyfert 2 galaxies. Significant correlations are found between the 2 keV X-ray flux and the nonstellar continuum near 3.5 microns, the nonstellar B band continuum, and the H-beta line flux, and also between 0.5-4.5 keV X-ray luminosity and the zero intensity width of the H-beta emission line and the H-beta forbidden O III ratio. These correlations apply to both types of Seyfert galaxy, as well as the X-ray selected QSOs of Gindlay et al., suggesting that the same physical process operates in each one over a continuous range of intrinsic luminosity. |
