We calculate simultaneously the radio and optical luminosity evolutions of quasars, and the distribution in radio loudness R defined as the ratio of radio and optical luminosities, using a flux limited data set containing 636 quasars with radio and optical fluxes from White et al. We first note that when dealing with multivariate data it is imperative to first determine the true correlations among the variables, not those introduced by the observational selection effects, before obtaining the… 
On the Radio and Optical Luminosity Evolution of Quasars II - The SDSS Sample
We determine the radio and optical luminosity evolutions and the true distribution of the radio loudness parameter R, defined as the ratio of the radio to optical luminosity, for a set of more than
MEAN AND EXTREME RADIO PROPERTIES OF QUASARS AND THE ORIGIN OF RADIO EMISSION
We investigate the evolution of both the radio-loud fraction (RLF) and (using stacking analysis) the mean radio loudness of quasars. We consider how these properties evolve as a function of redshift
The Mid-Infrared Luminosity Evolution and Luminosity Function of Quasars with WISE and SDSS
We determine the 22 μm luminosity evolution and luminosity function for quasars from a data set of over 20,000 objects obtained by combining flux-limited Sloan Digital Sky Survey optical and Wide
On the relation between the AGN jet and accretion disk emissions
Abstract AGN jets are detected via their radio and/or gamma-ray emissions while the accretion disks are detected by their optical and UV radiation. Observations of the radio and optical luminosities
Luminosity–Luminosity Correlations in Flux-limited Multiwavelength Data
We explore the general question of correlations among different waveband luminosities in a flux-limited multiband observational data set. Such correlations, often observed for astronomical sources,
Waveband Luminosity Correlations in Flux-Limited Multiwavelength Data
We explore the general question of correlations among different waveband luminosities in a fluxlimited multiband observational data set. Such correlations, often observed for astronomical sources,
Herschel-ATLAS: far-infrared properties of radio-loud and radio-quiet quasars
We have constructed a sample of radio-loud and radio-quiet quasars from the Faint Images Radio Sky at Twenty-one centimetres and the Sloan Digital Sky Survey Data Release 7, over the Herschel-ATLAS
Gamma-ray Luminosity and Photon Index Evolution of FSRQ Blazars and Contribution to the Gamma-ray Background
We present the redshift evolutions and distributions of the gamma-ray luminosity and photon spectral index of flat spectrum radio quasar (FSRQ) type blazars, using non-parametric methods to obtain
Accounting for Selection Bias and Redshift Evolution in GRB Radio Afterglow Data
Gamma-ray Bursts (GRBs) are highly energetic events that can be observed at extremely high redshift. However, inherent bias in GRB data due to selection effects and redshift evolution can
Cosmological Evolution of Quasar Radio Emission in the View of Multifractality
Variations in scaling behavior in the flux and emissions of distant astronomical sources with respect to their cosmic time are important l phenomena that can provide valuable information about the

The luminosity function of quasars and its evolution: A comparison of optically selected quasars and quasars found in radio catalogs
The luminosity function of quasars and its evolution are discussed, based on comparison of available data on optically selected quasars and quasars found in radio catalogs. It is assumed that the red
A Comparison of the Optical Properties of Radio-loud and Radio-quiet Quasars
We have made radio observations of 87 optically selected quasars at 5 GHz with the VLA in order to measure the radio power for these objects and hence determine how the fraction of radio-loud quasars
Luminosity correlations in quasars
We investigate quasar luminosity correlations by means of a Monte Carlo analysis for various model distributions of quasars in X-ray and optical luminosity. The simulations are carried out both with

We present deep radio observations of the most distant complete quasar sample drawn from the Sloan Digital Sky Survey. Combining our new data with those from literature, we obtain a sample which is
An Observational Determination of the Bolometric Quasar Luminosity Function
We combine a large set of quasar luminosity function (QLF) measurements from the rest-frame optical, soft and hard X-ray, and near- and mid-IR bands to determine the bolometric QLF in the redshift
The radio-loud fraction of quasars is a strong function of redshift and optical luminosity
Using a sample of optically selected quasars from the Sloan Digital Sky Survey, we have determined the radio-loud fraction (RLF) of quasars as a function of redshift and optical luminosity. The

We use several quasar samples to determine the density and luminosity evolution of quasars. Combining different samples and accounting for varying selection criteria require tests of correlation and
X-ray and radio core emission in radio quasars
In order to investigate the physical relationship between X-ray and radio core emission in radio-selected quasars, 35 radio quasars have been observed with the VLA at 6 and 20 cm. The sample was
The radio-loud/radio-quiet dichotomy: news from the 2dF QSO Redshift Survey
We present a detailed analysis of a sample of radio-detected quasars, obtained by matching together objects from the FIRST survey and the 2dF Quasar Redshift Survey (2dF). The data set consists of
Thermal and Nonthermal Radio Galaxies
Radio galaxies were discovered and mapped in the 1950s. The optical spectra showed little or no nuclear continuum light. Some also revealed powerful high ionization emission lines, while others
