| dc.description | We derive an analytic model for the redshift evolution of linear-bias, allowing for interactions and merging of the mass-tracers, by solving a second order differential equation based on linear perturbation theory and the Friedmann-Lemaitre solutions of the cosmological field equations. We then study the halomass dependence of the bias evolution, using the dark matter halo distribution in a ΛCDM simulation in order to calibrate the free parameters of the model. Finally, we compare our theoretical predictions with available observational data and find a good agreement. In particular, we find that the bias of optical QSO’s evolve differently than those selected in X-rays and that their corresponding typical dark matter halo mass is ∼ 10¹³ h⁻¹ Mꙩ and ≿5 × 10¹³ h⁻¹ Mꙩ, respectively. | |
