The complex optical to soft x-ray spectrum of the low-redshift radio-quiet quasars
(IOP Publishing, 1994)
Eight high signal-to-noise ROSAT Position Sensitive Proportional Counter (PSPC) observations of six low-redshift (o.048 less than z less than 0.155) radio-quiet quasars have been analyzed to study ant soft excess. All the ...
The soft x-ray properties of a complete sample of optically selected quasars. 1: First results
(IOP Publishing, 1994)
We present the results of ROSAT position sensitive proportional counter (PSPC) observations of 10 quasars. These objects are part of our ROSAT program to observe a complete sample of optically selected quasars. This sample ...
Atlas of quasar energy distributions
(IOP Publishing, 1994)
We present an atlas of the spectral energy distributions (SEDs) of normal, nonblazar, quasars over the whole available range (radio to 10 keV X-rays) of the electromagnetic spectrum. The primary (UVSX) sample includes 47 ...
