TL;DR: In this paper, a semi-analytic model that self-consistently traces the growth of supermassive black holes and their host galaxies within the context of the Lambda cold dark matter (� CDM) cosmological framework is presented.

TL;DR: In this paper, the authors combine a large set of quasar luminosity function (QLF) measurements from the rest-frame optical, soft and hard X-ray, and near and mid-IR bands to determine the bolometric QLF in the redshift interval z = 0-6.

TL;DR: In this paper, the authors describe numerical methods for incorporating gas dynamics into cosmological simulations and present illustrative applications to the cold dark matter (CDM) scenario, which they describe a version of TreeSPH (Hernquist \& Katz 1989) generalized to handle comoving coordinates and periodic boundary conditions.

TL;DR: The authors of as mentioned in this paper showed that approximately 30%-40% of all baryons in the present-day universe reside in a warm-hot intergalactic medium (WHIM), with temperatures in the range 105 < T < 107 K. This is a generic prediction from six hydrodynamic simulations of currently favored structure formation models having a wide variety of numerical methods, input physics, volumes, and spatial resolutions.

TL;DR: In this paper, the color transformation induced by star formation and active galactic nuclei during major mergers of spiral galaxies is studied. But the authors assume that a small fraction of the bolometric luminosity of an accreting black hole couples thermally to surrounding gas, providing a feedback mechanism that regulates its growth.
