“…We do not include any redshift evolution, because it is still unclear whether there is an evolution, and whether it is in normalization or slope. This is still discussed both theoretically (Volonteri & Stark 2011;DeGraf et al 2015;Beckmann et al 2017) and observationally (Ding et al 2017, and references therein). For a given galaxy mass, we assign a BH mass based on Equation (1) and a luminosity through the probability distribution of the logarithmic Eddington ratio λ, recalling that l 38.11 l m = + + .…”

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.

“…Finally, the bottom panels of Fig. 10 present a comparison with the Horizon-AGN simulation (Dubois et al 2014), showing measurements presented in Beckmann et al (2017) 9 . Beckmann et al (2017 measure outflow rates for two 2 kpc thick shells at 20 % (bottom-left) and 95 % of the halo virial radius, and we plot their measurements as a function of stellar mass (without any aperture correction).…”

We present measurements of galactic outflow rates from the EAGLE suite of cosmological simulations. We find that gas is removed from the interstellar medium (ISM) of central galaxies with a dimensionless mass loading factor that scales approximately with circular velocity as V −3/2 c in the low-mass regime where stellar feedback dominates. Feedback from active galactic nuclei (AGN) causes an upturn in the mass loading for halo masses > 10 12 M . We find that more gas outflows through the halo virial radius than is removed from the ISM of galaxies, particularly at low redshift, implying substantial mass loading within the circumgalactic medium. Outflow velocities span a wide range at a given halo mass/redshift, and on average increase positively with redshift and halo mass up to M 200 ∼ 10 12 M . We present a number of like-for-like comparisons to outflow rates from other recent cosmological hydrodynamical simulations, and show that comparing the propagation of galactic winds as a function of radius reveals substantial discrepancies between different models. Relative to some other simulations, EAGLE favours a scenario for stellar feedback where agreement with the galaxy stellar mass function is achieved by removing smaller amounts of gas from the ISM, but with galactic winds that then propagate and entrain ambient gas out to larger radii.

“…Theoretical studies have been also undertaken to explain the effect of AGN feedback on the surrounding hot gas in galaxy groups and clusters (e.g., Hambrick et al 2011;Gaspari et al 2012;Choi et al 2015). To study the effect of AGN feedback on large scale structure and to evaluate its importance on the evolutionary history of the Universe, AGN feedback has been introduced in cosmological simulations (e.g., Zanni et al 2005;Sijacki et al 2007;Pelupessy et al 2007;Di Matteo et al 2008;Vogelsberger et al 2014a,b;Sijacki et al 2015;Genel et al 2014;Chatterjee et al 2008;Bhattacharya et al 2008;Johansson et al 2009;McCarthy et al 2010;Hirschmann et al 2014;Nelson et al 2015;Steinborn et al 2015;Li et al 2015;Schaye et al 2015;Liu et al 2016;Biernacki et al 2017;Beckmann et al 2017;Scholtz et al 2018;Peirani et al 2019).…”

In this study we quantify the properties of the gas and dark matter around active galactic nuclei (AGN) in simulated galaxy groups and clusters and analyze the effect of AGN feedback on the surrounding intra-cluster (group) medium. Our results suggest downsizing of AGN luminosity with host halo mass, supporting the results obtained from clustering studies of AGN. By examining the temperature and density distribution of the gas in the vicinity of AGN we show that due to feedback from the central engine, the gas gets displaced from the centre of the group/cluster resulting in a reduction of the density but an enhancement of temperature. We show that these effects are pronounced at both high and low redshifts and propose new observables to study the effect of feedback in higher redshift galaxies. We also show that the average stellar mass is decreased in halos in the presence of AGN feedback confirming claims from previous studies. Our work for the first time uses a fully cosmological-hydrodynamic simulation to evaluate the global effects of AGN feedback on their host dark matter halos as well as galaxies at scales of galaxy groups and clusters.
