Ultraviolet Observations of NGC 3516 using the Hopkins Ultraviolet Telescope
We observed the Seyfert 1 galaxy NGC 3516 twice during the flight of Astro-2 using the Hopkins Ultraviolet Telescope aboard the space shuttle Endeavour in March 1995. Simultaneous X-ray observations were performed with ASCA. Our far-ultraviolet spectra cover the spectral range 820–1840 Å with a resolution of 2–4 Å. No significant variations were found between the two observations. The total spe...

متن کاملThe Diffuse Ultraviolet Background Radiation
I review the nature of the diffuse cosmic ultraviolet background radiation. The ultraviolet background is the last frontier: all the other diffuse backgrounds have been examined, at least at some level. The ultraviolet background has only begun to be explored; it offers rich promise of new astrophysical knowledge.

متن کاملHopkins Ultraviolet Telescope Observations of Her X - 1
We have obtained a far-ultraviolet spectrum of the X-ray binary Hercules X1/HZ Herculis using the Hopkins Ultraviolet Telescope aboard the Astro-1 space shuttle mission in 1990 December. This is the first spectrum of Her X-1 that extends down to the Lyman limit at 912 Å. We observed emission lines of OVIλλ 1031.9, 1037.6, NVλλ 1238.8, 1242.8, and C IVλλ 1548.2, 1550.8, and the far UV continuum ...
