The X-Ray Luminosity Function of Active Galactic Nuclei
نویسنده
چکیده
We derive an X-ray luminosity function for active galactic nuclei (AGN) that accounts for the X-ray source counts in the 0.5–2.0 and 2–10 keV energy ranges, the redshift distribution of AGNs in the ROSAT Deep Survey (RDS), as well as the X-ray background (XRB) from 1–10 keV. We emphasize the role of X-ray absorption, which has a large effect on the faint end of the 2– 10 keV source counts, as well as on the integrated X-ray background.

Deep-Survey Constraints on X-ray Outbursts from Galactic Nuclei
Luminous X-ray outbursts with variability amplitudes as high as ∼ 1 000 have been detected from a small number of galactic nuclei. These events are likely associated with transient fueling of nuclear supermassive black holes. In this paper, we constrain X-ray outbursts with harder spectra, higher redshifts, and lower luminosities than have been studied previously. We performed a systematic surv...
متن کاملModeling active galactic nuclei: ongoing problems for the faint-end of the luminosity function
We consider simple semi-analytic models that relate the active galactic nuclei (AGN) evolution to the merging history of their host dark matter haloes and quantify their ability of matching the AGN luminosity function and its spatial clustering at low and intermediate redshifts. In particular, we focus on the recent determinations of the AGN luminosity function in the hard X-ray band at z ∼ 0 w...
متن کاملA Single Intrinsic Luminosity Function for Both Type-I and Type-II Active Galactic Nuclei
The luminous electromagnetic emission from distant active galactic nuclei (AGNs) including quasars is believed to be powered by accretion onto supermassive black holes (SMBHs). In the standard unification model for AGNs a dusty torus covers a significant portion of the viewing angles to the accretion disk and the BH. The system is classified as a type-I AGN if the accretion disk is viewed throu...
متن کاملOn the dependence of the iron K-line profiles with luminosity in Active Galactic Nuclei
We present evidence for changes in the strength and profile of the iron Kα line in Active Galactic Nuclei (AGN), based on X-ray observations with ASCA. There is a clear decrease in the strength of the line with increasing luminosity. This relation is is not due solely to radio power, as it persists when only radio-quiet AGN are considered and therefore cannot be fully explained by relativistic ...
متن کاملContribution of Stellar Tidal Disruptions to the X-Ray Luminosity Function of Active Galaxies
The luminosity function of active galactic nuclei has been measured down to luminosities ∼ 1042 ergs s−1 in the soft and hard X-rays. Some fraction of this activity is associated with the accretion of the material liberated by the tidal disruption of stars by massive black holes. We estimate the contribution to the X-ray luminosity function from the tidal disruption process. While the contribut...
