Michael Shull , & Wei Zheng ( STScI, CAS/JHU, Dept. of Physics and Astronomy, Univ. of Wyoming, KPNO/NOAO, HIA/NRC, CASA, Univ. of Colorado | | Abstract: | The Far Ultraviolet Spectroscopic Explorer (FUSE) has surveyed a large sample (> 100) of active galactic nuclei in the low redshift universe (z < 1). Its response at short wavelengths makes it possible to measure directly the EUV spectral shape of QSOs and Seyfert 1 galaxies at z < 0.3. Using archival FUSE spectra, we form a composite extreme ultraviolet (EUV) spectrum of QSOs at z < 1 and compare it to UV/optical composite spectra of QSOs at higher redshift, particularly the composite spectrum from archival Hubble Space Telescope spectra. | | Source: | arXiv, astro-ph/0403662 | | Services: | Forum | Review | PDF | Favorites | |
