The diversity of soft X-ray spectra in quasars
(IOP Publishing, 1985)
Soft X-ray spectra for three quasars obtained with the Einstein Imaging Proportional Counter covering the 0.1-4.0 keV band are reported. Power-law fits to these spectra have best-fit energy indices of 1.2 +0.6 or -0.2, for ...
PG0946 + 301 - A low-redshift, broad absorption line QSO
(IOP Publishing, 1985)
The discovery of a new broad absorption line (BAL) QSO with the lowest emisson-line redshift to date (z = 1.216) is reported. The data provide evidence for complex broad absorption up to velocities ≡14,500 km s-1 relative ...
