“…In this paper we study the properties of BHs with masses and accretion rates that span a wide range, often covering regions of the parameter space that are far from the typical "quasars" that are used as a benchmark to derive mean spectral energy distributions (SEDs; e.g., Elvis et al 1994;Vanden Berk et al 2001;Richards et al 2006;Elvis et al 2012) that are then used to derive fits for bolometric corrections (Marconi et al 2004;Hopkins et al 2007;Lusso et al 2012). See Jensen et al (2016) for a first attempt at using observations to constrain AGN redshift spectral evolution.…”

The first billion years of the Universe has been a pivotal time: stars, black holes (BHs), and galaxies formed and assembled, sowing the seeds of galaxies as we know them today. Detecting, identifying, and understanding the first galaxies and BHs is one of the current observational and theoretical challenges in galaxy formation. In this paper we present a population synthesis model aimed at galaxies, BHs, and active galactic nuclei (AGNs) at high redshift. The model builds a population based on empirical relations. The spectral energy distribution of galaxies is determined by age and metallicity, and that of AGNs by BH mass and accretion rate. We validate the model against observations, and predict properties of galaxies and AGN in other wavelength and/or luminosity ranges, estimating the contamination of stellar populations (normal stars and high-mass X-ray binaries) for AGN searches from the infrared to X-rays, and vice versa for galaxy searches. For high-redshift galaxies with stellar ages 1 Gyr < , we find that disentangling stellar and AGN emission is challenging at restframe UV/optical wavelengths, while high-mass X-ray binaries become more important sources of confusion in X-rays. We propose a color-color selection in the James Webb Space Telescope bands to separate AGN versus star-dominated galaxies in photometric observations. We also estimate the AGN contribution, with respect to massive, hot, and metal-poor stars, at driving high-ionization lines, such as C IV and He II. Finally, we test the influence of the minimum BH mass and occupation fraction of BHs in low-mass galaxies on the restframe UV/near-IR and X-ray AGN luminosity function.

“…GALEX and XMM optical monitor (OM) UV photometry is available for some objects (see table E1 of Paper I), however, due to the redshift range of our AGN, these data lie on or beyond Lyα. Photometry covering Lyα cannot be corrected because the equivalent width (EW) of this strong feature varies widely between objects (Elvis et al 2012). Similarly, photometry beyond Lyα in the rest frame cannot be reliably used, as it is unpredictably attenuated by the multitude of narrow absorption features in the Lyα forest.…”

We perform a spectral analysis of a sample of 11 medium redshift (1.5 z 2.2) quasars. Our sample all have optical spectra from the SDSS, infrared spectra from GNIRS and TSPEC, and X-ray spectra from XMM-Newton. We first analyse the Balmer broad emission line profiles which are shifted into the IR spectra to constrain black hole masses. Then we fit an energy-conserving, three component accretion model of the broadband spectral energy distribution (SED) to our multiwavelength data. Five out of the 11 quasars show evidence of an SED peak, allowing us to constrain their bolometric luminosity from these models and estimate their mass accretion rates. Based on our limited sample, we suggest that estimating bolometric luminosities from L 5100 Å and L 2−10 keV may be unreliable, as has been also noted for a low-redshift, X-ray selected AGN sample.
