ULTRAVIOLET SPECTRA OF THE NARROW-LINED SEYFERT GALAXIES MARKARIAN 573 AND MARKARIAN 1388

ULTRAVIOLET SPECTRA OF THE NARROW-LINED SEYFERT GALAXIES MARKARIAN 573 AND MARKARIAN 1388

Ultraviolet spectra, obtained with the IUE satellite, are presented for the unusually narrowlined Seyfert galaxies Mrk 573 and Mrk 1388. The data support class 2 identifications for both galaxies and also suggest the need for more energetic ionizing radiation in the most recently published Seyfert 2...

Zusammenfassung:Ultraviolet spectra, obtained with the IUE satellite, are presented for the unusually narrowlined Seyfert galaxies Mrk 573 and Mrk 1388. The data support class 2 identifications for both galaxies and also suggest the need for more energetic ionizing radiation in the most recently published Seyfert 2 galaxy photoionization calculation.
