Abstract:
We present lists of more than 80000 mostly UV-optical colour-selected
AGN from 12 data sets, homogenised with respect to the assumed
cosmology, magnitude system, and bandpass correction (if possible). We
also present the selection functions for each of the 12 data sets,
similarly homogenised. The total sample spans redshifts from z=0 to
7.5. The paper presents a detailed description of the combined sample
and determinations of the AGN UV luminosity function throughout this
redshift range. The code for developing and analysing AGN luminosity
functions is available on GitHub (https://github.com/gkulkarni/QLF).
The inferred UV luminosity functions can also be used to derive the
contribution of AGN to the cosmic UV background and its effect on the
intergalactic medium (IGM). The GitHub repository also includes code
for this. Here we also present the luminosity functions in redshift
bins, luminosity function evolution models from the paper, the 912Å
and 1450Å volume emissivity of AGN from z=0 to 15, and the hydrogen
photoionization rate contribution by AGN in this redshift range.
Description:
We have analysed the evolution of the AGN UV luminosity function from
redshift z=0 to 7.5 using a combined sample of 83488 mostly
UV-optical colour-selected AGN from 12 data sets, homogenized with
respect to the assumed cosmology, magnitude system, and bandpass
correction (if possible). The vast majority of them (83469 AGN from
11/12 samples) have spectroscopic redshifts, and for all but 22 AGN
the selection functions have been characterized. After restricting the
sample due to persisting incompleteness at the faint end, we arrive at
77659 spectroscopically confirmed 0<z<7.5 AGN extending to absolute AB
magnitudes M1450~=-19 at z~=0.5 and to M1450~=-22 at z>3.5,
respectively. To facilitate comparisons to future data sets, we make
the homogenized AGN sample and the homogenized selection functions
publicly available.

corr account for the sensitivity limit, which for other surveys
is usually included in p. corr was calculated by taking the
ratio of derived phi (using uncorrected selection probabilities)
with the phi reported by Giallongo et al. (2015A&A...578A..83G 2015A&A...578A..83G).
