Anisotropic AGN Outflows Filling The Cosmological Volume

TL;DR

This paper simulates anisotropic AGN outflows within a cosmological volume to assess their large-scale impact, revealing that up to a quarter of the universe's volume is influenced by these outflows with magnetic fields.

Contribution

It introduces a novel simulation of anisotropic AGN outflows in a cosmological context using observed luminosity functions and analytical models.

Findings

13-25% of the universe's volume is filled with AGN outflows by present day

Outflows contain magnetic fields of approximately 10^{-9} G

The study links AGN activity to large-scale magnetic field distribution

Abstract

We simulate anisotropic outflows of AGN, and investigate the large-scale impact of the cosmological population of AGN outflows over the Hubble time by performing N-body LambdaCDM simulations. Using the observed quasar luminosity function to get the redshift and luminosity distribution, and analytical models for the outflow expansion, AGNs are allowed to evolve in a cosmological volume. By the present epoch, 13 - 25% of the total volume is found to be pervaded by AGN outflows, with 10^{-9} G magnetic field.
