Quasar spectra and the K correction
A new determination of the optical K(z) relation for QSOs is presented, derived from multiwavelength photometry of 25 low-redshift QSOs. The relation deviates strongly from the simple picture of single power law spectra as an overall description, but also from previous empirical determinations based on composite spectra. The deviations are particularly significant at low redshifts where K(z) dr...
متن کاملLuminosity-dependent Quasar Lifetimes: a New Interpretation of the Quasar Luminosity Function
We propose a new interpretation of the quasar luminosity function (LF), derived from physically motivated models of quasar lifetimes and light curves. In our picture, quasars evolve rapidly and their lifetime depends on both their instantaneous and peak luminosities. We study this model using simulations of galaxy mergers that successfully reproduce a wide range of observed quasar phenomena. Wi...
متن کاملThe UVX quasar optical luminosity function and its evolution
The recently-finished Edinburgh UVX quasar survey at B < 18 is used together with other complete samples to estimate the shape and evolution of the optical luminosity function in the redshift range 0.3 < z < 2.2. There is a significantly higher space density of quasars at high luminosity and low redshift than previously found in the PG sample of Schmidt & Green (1983), with the result that the ...
متن کاملDeriving the Quasar Luminosity Function from Accretion Disk Instabilities
We have derived the quasar luminosity function assuming that the quasar activity is driven by a thermal-viscous unstable accretion disk around a supermassive black hole. The instabilities produce large amplitude, long-term variability of a single source. We take a light curve of a single source and calculate the luminosity function, from the function of time it spends at each luminosity. Convol...
متن کاملAn 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 nearand mid-infrared bands to determine the bolometric QLF in the redshift interval z = 0 − 6. Accounting for the observed distributions of quasar column densities and variation of spectral energy distribution (SED) shapes, and their dependence on luminosity, makes it po...
