Using a sample of 228 optically selected active galactic nuclei (AGNs) in the 0.01–6.3 redshift range with a high fraction of X-ray detections (81%–86%), we study the relation between rest-frame UV and soft X-ray emission and its evolution with cosmic time. The majority of the AGNs in our sample (155 objects) have been selected from the Sloan Digital Sky Survey (SDSS) in an unbiased way, rendering the sample results representative of all SDSS AGNs. The addition of two heterogeneous samples of… Expand
The X-Ray-to-Optical Properties of Optically Selected Active Galaxies over Wide Luminosity and Redshift Ranges
We present partial-correlation analyses that examine the strengths of the relationships between l2500 A, l2 keV, αOX, and redshift for optically selected active galactic nuclei (AGNs). We extend theExpand
The X-ray to optical-UV luminosity ratio of X-ray selected type 1 AGN in XMM-COSMOS
We present a study of the X-ray to optical properties of a sample of 545 X-ray selected type 1 AGN, from the XMM-COSMOS survey, over a wide range of redshifts (0.04 \textless z \textless 4.25) andExpand
An X-ray survey in SA 57 with XMM-Newton
Context. The maximum number density of Active Galactic Nuclei (AGNs), as deduced from X-ray studies, occurs at z < 1, with lower luminosity objects peaking at smaller redshifts. Optical studies leadExpand
Optical-to-X-ray emission in low-absorption AGN: results from the Swift–BAT 9-month catalogue

The correlation of narrow line emission and X-ray luminosity in active galactic nuclei
Aims. We combine emission line and X-ray luminosities for 45 sources from the Chandra Deep Field South (CDF-S), and seven HELLAS sources, to obtain a new sample of 52 X-ray selected type-II activeExpand
Measuring the Sources of the Intergalactic Ionizing Flux
We use a wide-field (0.9 deg2) X-ray sample with optical and Galaxy Evolution Explorer (GALEX) ultraviolet observations to measure the contribution of active galactic nuclei (AGNs) to the ionizingExpand
Variability and spectral energy distributions of low-luminosity active galactic nuclei: a simultaneous X-ray/UV look with Swift

The soft X-ray properties of quasars in the Sloan Digital Sky Survey
We use the ROSAT All-Sky Survey (RASS) to study the soft X-ray properties of a homogeneous sample of 46 420 quasars selected from the third data release of the Sloan Digital Sky Survey (SDSS).Expand
The tight relation between X-ray and ultraviolet luminosity of quasars
The observed relation between the soft X-ray and the optical-ultraviolet emission in active galactic nuclei (AGN) is non-linear and it is usually parametrized as a dependence between the logarithm ofExpand
Evolution of the X-ray Emission of Radio-quiet Quasars
We report new Chandra observations of seven optically faint, z ~ 4 radio-quiet quasars (RQQs). We have combined these new observations with previous Chandra observations of RQQs to create a sample ofExpand
