填充宇宙学体积的各向异性AGN流出

Anisotropic AGN Outflows Filling The Cosmological Volume

Paramita Barai, Joel Germain, Hugo Martel

摘要:

我们模拟了活动星系核的各向异性外流,并通过N体LambdaCDM模拟研究了哈勃时间内活动星系核外流宇宙学布居的大尺度影响。利用观测到的类星体光度函数得到红移和光度分布,并利用外流膨胀的解析模型,使活动星系核在宇宙学体积内演化。到目前为止,活动星系核外流已占总体积的13 - 25%,其磁场为10^{-9} G。

英文摘要:

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.
