摘要:

事件视界望远镜(EHT)提供了一个独特的机会,通过甚大基线干涉测量(VLBI)探测超大质量黑洞的物理,如事件视界的存在,吸积过程以及喷流的形成。我们建立了一个理论模型,其中包括一个平流主导的吸积流(ADAF)和一个简单的无线电喷流流出。将该模型的预测谱能量分布(SED)与观测值进行比较,以获得模型参数的最佳估计。此外,模型预测的径向辐射分布在不同的频带可以用来预测是否流入可以解决的EHT。

英文摘要:

The Event Horizon Telescope (EHT) provides a unique opportunity to probe the physics of supermassive black holes through Very Large Baseline Interferometry (VLBI), such as the existence of the event horizon, the accretion processes as well as jet formation. We build a theoretical model which includes an Advection Dominated Accretion Flow (ADAF) and a simple radio jet outflow. The predicted spectral energy distribution (SED) of this model is compared to observations to get the best estimates of the model parameters. Also the model-predicted radial emission profiles at different frequency bands can be used to predict whether the inflow can be resolved by the EHT.
