论文摘要
Radio-Loud（RL）活性银河核（AGN）是所有波长最明亮的天体物理来源之一。他们的相对论喷射会影响其超级质量黑洞（SMBH）的生长和周围的白术培养基。虽然在无线电带中可以观察到这些喷气机在所有尺度（从PC到MPC尺度）上观察到，但预计它们的X射线和γ射线发射将集中在非常小的尺度上（<10 PC）。但是，在Chandra X射线望远镜推出后，检测到了几次KPC规模的喷气机，并且在这些尺度上导致其高能辐射的机制仍在争论中。了解其起源对于在很大的规模上得出这些喷气机（例如力量）的物理特性以及其对环境的影响至关重要。在下文中，我们探讨了相对论喷气机中相对论电子与宇宙微波背景光子（IC/CMB）的反向相互作用，作为可能的解释。此外，我们还估计，这种解释还可以影响托管在喷射系统中的SMBH的宇宙时代的观察到的演变。
Radio-Loud (RL) Active Galactic Nuclei (AGNs) are among the brightest astrophysical sources at all wavelengths. Their relativistic jets can affect both their Supermassive Black Holes (SMBHs) growth and the surrounding intergalactic medium. While in the radio band these jets can be observed at all scales (from pc to Mpc scales), their X-ray and γ-ray emission is expected to be concentrated on very small scales (<10 pc). However, after the launch of the Chandra X-ray telescope, several kpc-scale jets were detected and the mechanism responsible for their high-energy radiation at these scales is still under debate. Understanding its origin is crucial also to derive the physical properties of these jets (e.g. the power) at large scales and, as a consequence, their impact on the environment. In the following, we explore the Inverse Compton interaction of the relativistic electrons within relativistic jets with the Cosmic Microwave background photons (IC/CMB) as possible interpretation. Moreover, we also estimate how this interpretation could also affect the observed evolution across cosmic times of the SMBHs hosted in jetted systems.
