Coevolution of dark matter halos and black holes

ASTR SOC P 379 (2007) 273-275

Authors:

A Babic, L Miller, W Percival, S Croorn

Abstract:

We investigate a model of the coevolution of black holes and dark matter halos. The evolution of dark matter halos is based on the Press-Schechter theory. Assuming a simple relation between dark matter halos and supermassive black holes enables us to reproduce both the observed evolving hard X-ray luminosity function and the X-ray background.

GaIICS: A hybrid approach to cosmological chemodynamics

EAS PUBLICATIONS 24 (2007) 215-220

Abstract:

This contribution addresses the issue of metal enrichment and the distribution of metals in the lSN/IGM/ICM within the framework of a hybrid N-body plus semi-analytic method. It discusses its impact on galaxy bimodality and multi-wavelength galaxy counts.
