PublicaciónVariability of NGC 5543: The continuum
Simultaneous UV and optical variations of NGC 5548 suggest a common origin of the continuum flux at both ranges. If the bulk of the UV flux had a black body...

PublicaciónVariability of NGC 5548: The lines
Two broad components in the strongest UV emission lines of NGC 5548 are identified. The components respond differently to continuum changes. A normal broad...
